Description
CATO manufactures 2-Oxo-1,2-dihydrobenzo[cd]indole-5-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.
2-Oxo-1,2-dihydrobenzo[cd]indole-5-carboxylic acid (CAS 61035-49-2), molecular formula C12H7NO3 and molecular weight 213.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Oxo-1,2-dihydrobenzo[cd]indole-5-carboxylic acid (C12H7NO3) 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 its high hydrophobicity (logP), 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
