Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
7-Oxo-7H-benzo[de]benzo[4,5]imidazo[2,1-a]isoquinoline-4-carboxylic acid (CAS 52029-85-3), molecular formula C19H10N2O3 and molecular weight 314.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Oxo-7H-benzo[de]benzo[4,5]imidazo[2,1-a]isoquinoline-4-carboxylic acid (C19H10N2O3) is characterized by a steroid core, 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.
CATO manufactures 7-Oxo-7H-benzo[de]benzo[4,5]imidazo[2,1-a]isoquinoline-4-carboxylic acid 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.
