Chemical Structure
Description
The occurrence of (S)-3-((Acetamidomethyl)thio)-2-amino-3-methylbutanoic acid hydrochloride 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.
(S)-3-((Acetamidomethyl)thio)-2-amino-3-methylbutanoic acid hydrochloride (CAS 1330286-48-0), molecular formula C8H16N2O3SHCl and molecular weight 256.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-3-((Acetamidomethyl)thio)-2-amino-3-methylbutanoic acid hydrochloride (C8H16N2O3SHCl) 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.
