Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-methylsulphonyloxyoctadeca-9Z,12Z-diene.
1-methylsulphonyloxyoctadeca-9Z,12Z-diene (CAS 51154-39-3) is a high-purity analytical reference standard with the molecular formula C19H36O3S and a molecular weight of 344.55 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 1-methylsulphonyloxyoctadeca-9Z,12Z-diene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 344.55 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.
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.
