Flavour and fragrance chemistry draws on a large palette of small molecules, each with a distinct odour or taste. This sub-category supplies aroma chemicals and related intermediates, from citrus and floral notes to roasted and savoury ones. Examples include (±)-Citronellal 98%, 2-Acetylthiophene, 2-Ethylhexyl acetate, 2-Ethylhexanol, and fatty alcohols such as 1-Heptanol, 1-Decanol and 1-Undecanol.

Perfumers and flavourists judge materials by odour profile, strength and stability as much as by GC purity. Trace impurities can change a note noticeably, so the same specification from lot to lot is valued. Flavour use also requires compliance with food regulations, and fragrance use with industry standards on restricted materials.

Aroma chemicals ship in sealed glass, aluminium or HDPE containers, often under nitrogen to prevent oxidation. Each lot comes with a COA and SDS. Samples can be arranged for olfactory evaluation before bulk orders. Ask about regulatory status for your intended use when you enquire.

Flavour & Fragrance Chemicals: questions buyers ask

How should aroma chemicals be stored to keep their odour?
Keep them in full, tightly closed containers in a cool, dark place, ideally flushed with nitrogen. Aldehydes such as citronellal oxidise to acids in air, which dulls or sours the note. Smaller containers reduce headspace and repeated air exposure. Check odour against a retained sample before using older stock.
Is GC purity enough to judge an aroma chemical?
Not entirely. Two lots with the same GC purity can smell different because of trace impurities with strong odours. Perfumers usually compare new lots against an approved standard on a smelling strip. Use the COA for purity and physical data, and add sensory evaluation for final approval.
Can these chemicals be used in food flavours?
Some are permitted flavouring substances and others are not, depending on the regulation in your market. Food use also needs a suitable grade and documentation. Tell us the intended application and region, and we will confirm whether a flavour-grade version with the right paperwork is available.
