Ethosuximide-d5 CAS 1989660-59-4 chemical structure

Description

CATO manufactures Ethosuximide-d5 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.

CATO supplies Ethosuximide-d5 (CAS 1989660-59-4), a certified reference material (molecular formula C7H6D5NO2, MW 146.20 g/mol) for analytical method development and quality control.

The molecular framework of Ethosuximide-d5 (C7H6D5NO2) is characterized by deuterium isotope labeling, an amino-acid-derived structure, an amide 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.
