Profile

2-Acetylpyrazine is curated in this catalog as a caramelized material, with a secondary reading of roasted.

On the strip it reads popcorn roasted nut earthy.

It is registered under CAS 22047-25-2.

The catalog records an average working dose of 0.5% Max%, which is a starting point for a trial rather than a limit.

How it behaves

volatility index 0.74 · the opening

A boiling point of 189 °C and a molecular weight of 122.12 g/mol give 2-Acetylpyrazine a volatility index of 0.74, which places it in the opening of a composition.

It leaves the strip early and does its work in the first minutes, before the heart arrives.

The index runs from 0 for a material that barely leaves the strip to 1 for one that flashes off, and it is computed from boiling point and molecular weight. Inside a real formula the surrounding materials shift where the boundaries fall, so a material can read differently there than it does here.

Questions about 2-Acetylpyrazine

What does 2-Acetylpyrazine smell like?

2-Acetylpyrazine reads as caramelized and roasted, described in the catalog as popcorn roasted nut earthy.

Is 2-Acetylpyrazine a top, heart or base note?

2-Acetylpyrazine sits in the opening. Its volatility index of 0.74 is computed from a boiling point of 189 °C and a molecular weight of 122.12 g/mol, rather than assigned by hand. It leaves the strip early and does its work in the first minutes, before the heart arrives.

How much 2-Acetylpyrazine should I use?

The catalog records an average working dose of 0.5% Max% for 2-Acetylpyrazine. Treat that as the starting point for a trial: the right dose depends on what else is in the formula and what you want it to do there.

What can I use instead of 2-Acetylpyrazine?

The closest materials in this catalog by olfactive profile and physical behaviour are 2-Acetylthiazole (92.6% match), Trimethylpyrazine (74.7% match) and Sotolon (67.3% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like 2-Acetylpyrazine. Ranking ignores price.

What is the CAS number for 2-Acetylpyrazine?

2-Acetylpyrazine is registered under CAS 22047-25-2 in this catalog.
