Description
Compared with other compounds in its class, the molecular weight of 187.24 g/mol gives 3-Phenyl-6,7-dihydro-1H-azepin-2(5H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Phenyl-6,7-dihydro-1H-azepin-2(5H)-one (CAS 129104-35-4), a certified reference material (molecular formula C12H13NO, MW 187.24 g/mol) for analytical method development and quality control.
The molecular framework of 3-Phenyl-6,7-dihydro-1H-azepin-2(5H)-one (C12H13NO) 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).
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 3-Phenyl-6,7-dihydro-1H-azepin-2(5H)-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.
