Description
As a certified reference material (CRM), 9-Methoxy-5,11-dimethyl-6H-pyrido[4,3-b]carbazol-1-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.
9-Methoxy-5,11-dimethyl-6H-pyrido[4,3-b]carbazol-1-ol (CAS 72237-94-6) is a high-purity analytical reference standard with the molecular formula C18H16N2O2 and a molecular weight of 292.33 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 9-Methoxy-5,11-dimethyl-6H-pyrido[4,3-b]carbazol-1-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
