Chemical Structure

2,4-Dihydroxynicotinonitrile CAS 5657-64-7 chemical structure

Description

The molecular framework of 2,4-Dihydroxynicotinonitrile (C6H4N2O2) is characterized by 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

2,4-Dihydroxynicotinonitrile (CAS 5657-64-7), molecular formula C6H4N2O2 and molecular weight 136.11 g/mol, is a CATO reference standard with documented purity and traceability.

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 2,4-Dihydroxynicotinonitrile 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.
