Chemical Structure

1-Phenyl-1H-indazol-3(2H)-one CAS 28561-80-0 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1-Phenyl-1H-indazol-3(2H)-one (CAS 28561-80-0), molecular formula C13H10N2O and molecular weight 210.23 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Phenyl-1H-indazol-3(2H)-one (C13H10N2O) 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 its high hydrophobicity (logP), 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 1-Phenyl-1H-indazol-3(2H)-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.
