Chemical Structure
Description
CATO supplies (r)-3-Amino-3-(5-methylthiophen-2-yl)propanoic acid (CAS 1270272-47-3), a certified reference material (molecular formula C8H11NO2S, MW 185.24 g/mol) for analytical method development and quality control.
The molecular framework of (r)-3-Amino-3-(5-methylthiophen-2-yl)propanoic acid (C8H11NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-methylthiophen-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.
