7-Methylquinoxalin-2(1H)-one CAS 5762-65-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Methylquinoxalin-2(1H)-one.

7-Methylquinoxalin-2(1H)-one (CAS 5762-65-2), molecular formula C9H8N2O and molecular weight 160.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-Methylquinoxalin-2(1H)-one (C9H8N2O) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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 7-Methylquinoxalin-2(1H)-one 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.
