Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-Oxobenzo[cd]indol-1(2H)-yl)acetic acid.
2-(2-Oxobenzo[cd]indol-1(2H)-yl)acetic acid (CAS 39273-46-6), molecular formula C13H9NO3 and molecular weight 227.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(2-Oxobenzo[cd]indol-1(2H)-yl)acetic acid (C13H9NO3) 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.
As a certified reference material (CRM), 2-(2-Oxobenzo[cd]indol-1(2H)-yl)acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
