Chemical Structure

4-Methyl-2-(2-methyl-1-propenyl)tetrahydropyran (cis- and trans- mixture) CAS 16409-43-1 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

CATO supplies 4-Methyl-2-(2-methyl-1-propenyl)tetrahydropyran (cis- and trans- mixture) (CAS 16409-43-1), a certified reference material (molecular formula C10H18O, MW 154.25 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, 4-Methyl-2-(2-methyl-1-propenyl)tetrahydropyran (cis- and trans- mixture) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
