Chemical Structure
Description
3-Chloro-10-phenylacridin-9(10H)-one (CAS 5472-22-0), molecular formula C19H12ClNO and molecular weight 305.76 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Chloro-10-phenylacridin-9(10H)-one (C19H12ClNO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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), 3-Chloro-10-phenylacridin-9(10H)-one 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.
