Profile

Nonanal is curated in this catalog as an aldehydic material, with a secondary reading of waxy.

On the strip it reads waxy aldehydic rose.

It is registered under CAS 124-19-6.

The catalog records an average working dose of 1% Max%, which is a starting point for a trial rather than a limit.

How it behaves

volatility index 0.72 · the opening

A boiling point of 191.1 °C and a molecular weight of 142.24 g/mol give Nonanal a volatility index of 0.72, 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 Nonanal

What does Nonanal smell like?

Nonanal reads as aldehydic and waxy, described in the catalog as waxy aldehydic rose.

Is Nonanal a top, heart or base note?

Nonanal sits in the opening. Its volatility index of 0.72 is computed from a boiling point of 191.1 °C and a molecular weight of 142.24 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 Nonanal should I use?

The catalog records an average working dose of 1% Max% for Nonanal. 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 Nonanal?

The closest materials in this catalog by olfactive profile and physical behaviour are Dodecanal (99% match), Octanal (77.8% match) and Aldehyde C-10 (decanal) (76% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like Nonanal. Ranking ignores price.

What is the CAS number for Nonanal?
