Methylionone (mixture of alpha- and beta-, predominantly alpha-n-isomer) TCI M0363

TCI M0363 Methylionone is a cyclic terpenoid ketone supplied as a mixture of alpha- and beta-isomers, with the alpha-n-isomer present as the predominant component. The compound belongs to the ionone family, a group of aroma molecules naturally associated with the scent of violet flowers and iris root. In the laboratory, Methylionone serves as a reference material and test substance in natural product chemistry research, flavour and fragrance chemistry, and terpenoid studies. Its supply as an isomer mixture reflects the grade of material used in applied research, making it relevant for both formulation development and sensory evaluation work.

The characteristic that makes this compound a frequent choice is its cyclohexene framework conjugated with an unsaturated carbonyl group, an arrangement that gives the molecule a distinctive ultraviolet absorption together with the reactivity expected of a conjugated ketone. The material is a liquid, so it is straightforward to pipette, dilute, and inject directly into gas chromatography systems. Its aroma is strong at low concentration, meaning only very small quantities are required for evaluation purposes, while its terpenoid nature makes it a good model compound for studying the behaviour of this class of molecules.

In Indonesian laboratories, TCI M0363 Methylionone is typically used in university and institutional research settings where natural product chemistry and flavour and fragrance work are carried out. It supports analytical method development, comparison against extracted or distilled samples, and teaching activities that introduce terpenoid chemistry. Research groups working on essential oil characterisation and applied formulation studies commonly require a well-defined reference of this type to anchor their analytical and sensory results.

• Natural product chemistry research, where Methylionone serves as a defined terpenoid reference against which constituents isolated from plant extracts can be compared and identified.
• Flavour and fragrance chemistry studies, since the compound belongs to the ionone family associated with violet and iris aroma profiles relevant to formulation work.
• Gas chromatography method development, because the liquid form allows direct injection, dilution, and preparation of calibration series without additional dissolution steps beforehand.
• Terpenoid behaviour studies, as the conjugated cyclohexene and carbonyl arrangement makes the molecule a convenient model for examining reactivity within this compound class.
• Sensory evaluation and screening work, where the strong aroma at low concentration means only very small quantities are needed for each assessment carried out.

• Chemical description: mixture of alpha- and beta-isomers, predominantly the alpha-n-isomer

Store the container tightly closed in a cool, dry, well-ventilated area away from heat sources, open flames, and direct sunlight, following the storage conditions indicated on the product label. Amber glass bottles with chemically resistant closures are suitable, as they limit light exposure and reduce loss of volatile material. Handle the liquid inside a fume hood, since the aroma is strong even at low concentration and vapour can accumulate quickly in an enclosed space. Wear safety glasses, gloves, and a laboratory coat during transfer and dilution. Return the container promptly after dispensing, keep it clearly labelled, and consult the supplier safety data sheet before first use.
