The occurrence of N-(6-Chloro-9H-pyrido[3,4-b]indol-8-yl)nicotinamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(6-Chloro-9H-pyrido[3,4-b]indol-8-yl)nicotinamide (CAS 431898-65-6), molecular formula C17H11ClN4OHCl and molecular weight 359.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(6-Chloro-9H-pyrido[3,4-b]indol-8-yl)nicotinamide (C17H11ClN4OHCl) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), N-(6-Chloro-9H-pyrido[3,4-b]indol-8-yl)nicotinamide 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.
