Propionic acid, 3-mercapto-, 6-methylheptyl ester CAS 89136-90-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Propionic acid, 3-mercapto-, 6-methylheptyl ester.

Propionic acid, 3-mercapto-, 6-methylheptyl ester (CAS 89136-90-3) is a high-purity analytical reference standard with the molecular formula C11H22O2S and a molecular weight of 218.36 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Propionic acid, 3-mercapto-, 6-methylheptyl ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.36 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
