Profile

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

On the strip it reads fatty citrus orange peel waxy.

It is registered under CAS 124-13-0.

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 0.76 · the opening

A boiling point of 171 °C and a molecular weight of 128.21 g/mol give Octanal a volatility index of 0.76, 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 Octanal

What does Octanal smell like?

Octanal reads as aldehydic and zesty, described in the catalog as fatty citrus orange peel waxy.

Is Octanal a top, heart or base note?

Octanal sits in the opening. Its volatility index of 0.76 is computed from a boiling point of 171 °C and a molecular weight of 128.21 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 Octanal should I use?

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

The closest materials in this catalog by olfactive profile and physical behaviour are Aldehyde C-10 (decanal) (95.7% match), Citral (natural) (93.6% match) and Heptanal (77.7% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like Octanal. Ranking ignores price.

What is the CAS number for Octanal?

Octanal is registered under CAS 124-13-0 in this catalog.
