6810-12-4 99JNR46OKX Methionine hydrochloride UNII-99JNR46OKX (2S)-2-Amino-4-methylsulfanylbutanoic acid,hydrochloride L-Methionine monohydrochloride L-Methionine, hydrochloride L-Methionine, hydrochloride (1:1) Methionine, L-, hydrochloride CAS 6810-12-4 chemical structure

Description

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 6810-12-4 99JNR46OKX Methionine hydrochloride UNII-99JNR46OKX (2S)-2-Amino-4-methylsulfanylbutanoic acid,hydrochloride L-Methionine monohydrochloride L-Methionine, hydrochloride L-Methionine, hydrochloride (1:1) Methionine, L-, hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies 6810-12-4 99JNR46OKX Methionine hydrochloride UNII-99JNR46OKX (2S)-2-Amino-4-methylsulfanylbutanoic acid,hydrochloride L-Methionine monohydrochloride L-Methionine, hydrochloride L-Methionine, hydrochloride (1:1) Methionine, L-, hydrochloride (CAS 6810-12-4), a certified reference material (molecular formula C5H11NO2SHCl, MW 185.67 g/mol) for analytical method development and quality control.

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.
