Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
(R)-Benzyl 2-amino-3-(4-hydroxyphenyl)propanoate 4-methylbenzenesulfonate (CAS 97984-63-9), molecular formula C16H17NO3C7H8O3S and molecular weight 443.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R)-Benzyl 2-amino-3-(4-hydroxyphenyl)propanoate 4-methylbenzenesulfonate (C16H17NO3C7H8O3S) is characterized by a flavonoid core, 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).
CATO manufactures (R)-Benzyl 2-amino-3-(4-hydroxyphenyl)propanoate 4-methylbenzenesulfonate 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.
