Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 6P9E788VZZ 5421-46-5 Acetic acid, mercapto-, monoammonium salt Ammonium mercaptoacetate Ammonium thioglycolate Mercaptoacetic acid, monoammonium salt Acetic acid, 2-mercapto-, ammonium salt (1:1) AI3-26246 Ammonium thioglycollate EINECS 226-540-9 NSC 6954 Thiofaco A-50 Thioglycolic acid ammonium salt Thioglycollic acid, ammonium salt USAF MO-2 HSDB 7167 UNII-6P9E788VZZ EC 226-540-9 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 109.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
