Chemical Structure
Description
CATO supplies (r)-3-Amino-3-(5-chlorothiophen-2-yl)propanoic acid (CAS 1270060-15-5), a certified reference material (molecular formula C7H8ClNO2S, MW 205.66 g/mol) for analytical method development and quality control.
(r)-3-Amino-3-(5-chlorothiophen-2-yl)propanoic acid (C7H8ClNO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (r)-3-Amino-3-(5-chlorothiophen-2-yl)propanoic acid 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.
