Chemical Structure
Description
CATO manufactures (R)-2-Amino-3-((methylsulfonyl)thio)propanoic acid hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
(R)-2-Amino-3-((methylsulfonyl)thio)propanoic acid hydrochloride (CAS 37556-48-2) is a high-purity analytical reference standard with the molecular formula C4H9NO4S2HCl and a molecular weight of 235.70 g/mol.
The molecular framework of (R)-2-Amino-3-((methylsulfonyl)thio)propanoic acid hydrochloride (C4H9NO4S2HCl) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group, 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.
