Chemical Structure
Description
CATO supplies (1,1-Dioxidobenzo[d]isothiazol-3-yl)-l-phenylalanine (CAS 869651-65-0), a certified reference material (molecular formula C16H14N2O4S, MW 330.36 g/mol) for analytical method development and quality control.
The molecular framework of (1,1-Dioxidobenzo[d]isothiazol-3-yl)-l-phenylalanine (C16H14N2O4S) 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. 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 (1,1-Dioxidobenzo[d]isothiazol-3-yl)-l-phenylalanine 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.
