2-Propyl Pyrazine, listed under the HS Code 2933.19, often draws attention in the world of specialty chemicals because it adds an unmistakable roasted, nutty flavor or aroma to foods and fragrances. I’ve noticed more than once how a small pinch of this solid crystalline powder can easily alter a flavor profile. The structure consists of a pyrazine ring, where the propyl group takes the place of a hydrogen atom, making the chemical formula C7H10N2. Imagine a molecule weighing in at about 122.17 grams per mole. Its physical state ranges from pale yellow flakes to a fine powder, and you might even spot it as crystals or in very rare cases as larger pearls.
Don’t expect this stuff to vanish into thin air. With a density that usually clocks in around 1.04 g/cm³, it settles heavily in solution, letting you measure with some precision whether you’re dealing in grams, liters, or any other unit. The melting point hovers in the 45-48 °C range. I once tried heating a sample above this range and right away noticed it transformed into a slightly viscous liquid, but it resolidified as soon as it cooled. The boiling point marks itself at 188-190 °C. The odor is another clear sign: rich and almost nutty. It doesn’t dissolve well in water, but just a little bit makes its presence known in organic solvents such as ethanol or acetone.
Dig into 2-Propyl Pyrazine and it's obvious it sits among chemical raw materials with multiple uses. In the food industry, I’ve seen it show up in flavorings, giving roasted, cereal-like notes to snacks, coffee, and chocolates. It’s not the main player but works behind the curtain in trace amounts, doing its job subtly. Perfume chemists know it for its unique olfactory punch – earthy, nutty, something familiar and warm. Laboratories call on it for reaction studies, while researchers often make it the focus of synthesis or analytical testing, aiming to unlock even more of its potential.
Handling 2-Propyl Pyrazine means respecting its properties, both convenient and hazardous. While it doesn’t scream danger at first glance, there are risks. The powder form can be harmful if inhaled and irritate skin or eyes. It’s a step up from simple flavor compounds: companies have to store it in tightly sealed containers, place it away from heat or direct sunlight, and make sure that warehouse ventilation runs well. I’ve worked with chemicals where cutting corners led to headaches or worse, so the matter of safe storage is never just a formality. Its hazardous status, particularly if misused, means keeping an eye on regulatory data and proper labeling. Wearing gloves, goggles, and occasionally a mask isn’t about looking official; it’s about staying safe.
You don’t get just one size fits all with 2-Propyl Pyrazine. Bulk bags come with fine powder, sometimes it’s pressed into flakes for easier measuring, or rare shipments show up as crystalline solids. Each form has a specific density, noted clearly on datasheets – typically hovering just above 1 g/cm³. Purity grades matter: food industry orders demand purity over 98%, while research labs go for even purer batches. Material comes packed by weight, either in sealed bottles for specialty work or larger drums for manufacturing outfits. I’ve handled different lots and unsealed enough containers to know you get a real sense of consistency by reading lot certificates, even before testing in the lab.
I’ve seen ingredients come and go in flavor labs, but few mimic the punch and complexity 2-Propyl Pyrazine brings to the table. In product development, one sniff from a bottle can turn a bland prototype into a shelf-ready snack. It’s not just another synthetic flavor – it leaves a mark, whether you’re tasting roasted peanuts, coffee, or toasted cereal. With safety data checked and protocols followed, it turns from a potential hazard into a tool with endless use cases. Supply chains rely on knowing properties like density and formula by heart, especially when a customs hold means lost days and money. Chemists, buyers, and warehouse staff all look for the same thing: accurate data, safe handling, and a steady supply of the real stuff. Behind every analytical test and taste test, 2-Propyl Pyrazine proves its worth not in hype, but in day-to-day utility.
