FAQ

Frequently Asked Questions

It has a strong, fresh, citrus-like odour, often compared to lemongrass or ripe lemons.

It can be both. It occurs naturally in some plants but is more commonly produced synthetically for industrial use.

That is its systematic IUPAC name, which precisely describes the position of the methyl group (carbon 6), the double bond (between carbons 5 and 6), and the ketone group (on carbon 2) on a seven-carbon (hept) chain.

In the low concentrations used in perfumery and flavours, it is generally recognised as safe. However, like many chemicals, it requires proper handling in its pure, concentrated form, following safety data sheet (SDS) guidelines.

Mnemonic

Think of 'METHYL' (like methanol, a simple alcohol) + 'HEPT' (like heptagon, 7 sides/carbons) + 'EN' (like ethylene, has a double bond) + 'ONE' (like ketone, a functional group). It's a 'seven-carbon methyl ketone with a double bond'.

Conceptual Metaphor

N/A. The term is a literal, compositional descriptor of molecular structure.
