L-Cysteine, N-acetyl-S-(3-chloro-2-hydroxypropyl)- CAS 97729-49-2

Description

The occurrence of L-Cysteine, N-acetyl-S-(3-chloro-2-hydroxypropyl)- is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies L-Cysteine, N-acetyl-S-(3-chloro-2-hydroxypropyl)- (CAS 97729-49-2), a certified reference material (molecular formula C8H14ClNO4S, MW 255.72 g/mol) for analytical method development and quality control.

The molecular framework of L-Cysteine, N-acetyl-S-(3-chloro-2-hydroxypropyl)- (C8H14ClNO4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
