Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,11-Dimethyl-6H-pyrido[4,3-b]carbazol-9-ol.
CATO supplies 5,11-Dimethyl-6H-pyrido[4,3-b]carbazol-9-ol (CAS 51131-85-2), a certified reference material (molecular formula C17H14N2O, MW 262.31 g/mol) for analytical method development and quality control.
5,11-Dimethyl-6H-pyrido[4,3-b]carbazol-9-ol (C17H14N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 5,11-Dimethyl-6H-pyrido[4,3-b]carbazol-9-ol 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.
