74328-61-3 8-Mercaptooctanoic acid 8-Thiooctanoic acid MOA CAS 74328-61-3 chemical structure

Description

74328-61-3 8-Mercaptooctanoic acid 8-Thiooctanoic acid MOA (CAS 74328-61-3) is a high-purity analytical reference standard with the molecular formula C8H16O2S and a molecular weight of 176.28 g/mol.

74328-61-3 8-Mercaptooctanoic acid 8-Thiooctanoic acid MOA (C8H16O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
