Why This Guide Exists (My $890 Mistake)
In my first year at Chemours (2017), I submitted an order for industrial hydrochloric acid with the concentration specified incorrectly. Looked fine on my screen – the supplier confirmed the formula HCl, which I'd double-checked. But when the tanker arrived, the concentration was 37% instead of the 20% we needed for the cleaning process. $890 worth of product had to be neutralized and disposed of, plus a 1-week production delay. That's when I learned: knowing the correct chemical formula is just the starting point, but there's a lot more that can go wrong.
I've now been handling chemical procurement orders for 8 years. I've personally made (and documented) 6 significant mistakes, totaling roughly $12,000 in wasted budget. Now I maintain our team's checklist to prevent others from repeating my errors. This guide covers three common confusions I see repeatedly – and the right approach depends on which situation you're in. There's no one-size-fits-all answer.
The Three Common Confusions (Scenarios)
Scenario 1: "It's Just HCl, Right?" (Hydrochloric Acid Formula)
This one seems simple. Hydrochloric acid chemical formula is HCl – everyone knows that. But what I learned the hard way is that the concentration, grade, and intended use make all the difference. In September 2022, a new team member ordered "HCl" for a neutralization application. The supplier shipped reagent-grade (37%), when what we needed was technical-grade (20%) for a different pH adjustment. The order was for 4 drums – $450 wasted plus the embarrassment of explaining to the plant manager why we had to dispose of perfectly good acid.
What I mean is that the chemical formula only tells you the molecule, not the product. It's like knowing the word "blue" but not whether it's a sky blue or navy. The same HCl formula can come in concentrations ranging from 10% to 40%, with different impurities and intended applications. So if you're sourcing hydrochloric acid, don't just specify "HCl" – ask: What concentration? What grade? What will it be used for?
If you're a lab technician ordering for analytical chemistry, you need ACS-grade with precise concentration. If you're a plant manager ordering for industrial cleaning, technical-grade is fine. If you're a researcher developing a new formulation, you might need ultra-high purity. Different situations, different specs – and no single answer works for everyone.
Scenario 2: "That Green Pigment Must Be Chlorophyll" (Pigment That Makes Plants Green)
A customer once asked me: "What is the pigment that makes plants green? I need that for an organic coating." The answer is chlorophyll, of course, but here's the thing – chlorophyll is not a stable industrial pigment. It degrades in sunlight within hours. The question isn't what the pigment is; it's what you're actually trying to achieve. Are you looking for a natural green colorant? A UV-resistant green? A heat-stable green?
This gets into industrial pigment territory, which isn't my core expertise. But from a procurement perspective, I can tell you that most industrial green pigments are based on chromium oxide, phthalocyanine green, or synthetic iron oxides – not chlorophyll. If you're specifying a green pigment for a coating that will go on outdoor equipment, you need something with lightfastness ratings (ASTM D4303) above 7. Chlorophyll would fail immediately (unfortunately).
Interestingly, coating formulators often use titanium dioxide (TiO₂) – which Chemours produces as Ti-Pure™ – as a white base and then add colored pigments to achieve the desired shade. So when someone asks me about "the pigment that makes plants green," I first clarify their context. If you're formulating a garden paint that mimics foliage, you might want specific organic pigments that are light-stable. If you're just curious about biology, chlorophyll is the answer. If you're seeking a green pigment for industrial coatings, you're looking at synthetic options. The best choice depends entirely on your application.
Scenario 3: "Coatings and Fillings – It's All Paint, Isn't It?" (Coatings and Fillings Market)
Early in my career, I assumed "coatings" and "fillings" were the same thing. When a client asked about our position in the coatings and fillings market, I proudly said we dominate both. But fillings (in the context of industrial materials) refers to fillers – like calcium carbonate or talc – used to bulk up plastics, paper, or putties. Coatings are surface treatments like paints, varnishes, and protective layers. Chemours is a leader in coatings (our Teflon™ fluoropolymer coatings and Ti-Pure™ titanium dioxide pigments are used by major paint manufacturers), but we don't produce fillers. I had to backtrack quickly (ugh, embarrassing).
Why does this matter? Because if you're sourcing materials for a paint formulation, you need to distinguish between the coating itself (binder, pigment, solvent) and the fillers (extenders that modify rheology or reduce cost). A coating's performance depends on the pigment-to-binder ratio, and adding the wrong extender can ruin adhesion or durability. The coatings and fillings market is actually two distinct supply chains. If you're a paint formulator, you might use TiO₂ from Chemours for opacity, but get your calcium carbonate from a minerals supplier. If you're manufacturing caulks or sealants, you might need both a coating additive and a filler. The decision branches: Are you applying a thin film (coating) or building thickness (filler)?
How to Know Which Scenario You're In
Not sure which confusion applies to you? Here's a simple checklist (I keep this taped to my monitor):
- If you're ordering a chemical by its formula (like HCl), immediately ask: concentration, grade, application. Don't assume 'standard' exists.
- If you're asking about a natural pigment (like chlorophyll), clarify: is this for a product that needs light/heat stability, or just a biology question? If it's for a product, you probably need a synthetic pigment.
- If you're talking about 'coatings and fillings', define which side you're on: coating (thin, functional layer) or filler (bulk, cost-effective extender). They aren't interchangeable.
There's something satisfying about finally getting these distinctions right. After the third rejection in Q1 2024, I created this pre-check list – and we've caught 47 potential errors using it in the past 18 months. The best part: no more 3am worry sessions about whether the order will arrive correct.
What I Do Now (And What You Can Do)
I'm not a chemist, so I can't speak to the molecular details of every compound. What I can tell you from a procurement perspective is: always specify the intended use alongside the chemical name or formula. That one step would have saved me $890 in 2017. And when a customer asks a broad question (like "what pigment makes plants green?"), I ask three clarifying questions before recommending anything. If I'm uncertain, I consult our technical team – because recommending the wrong product is worse than not recommending at all (the honest limitation).
If you're an industrial buyer, my advice: build your own checklist based on the three scenarios above. If you're a formulator, remember that the best coating solution depends on your substrate, environment, and performance requirements – there's no universal best. I recommend Ti-Pure™ for titanium dioxide applications, but if you're dealing with extremely high-temp environments, you might want a ceramic coating alternative. Know your boundaries.
