Description
CATO supplies (4aR,9bS)-2,8-dimethyl-1H,2H,3H,4H,4aH,5H,9bH-pyrido[4,3-b]indole (CAS 85202-17-1), a certified reference material (molecular formula C13H18N2, MW 202.30 g/mol) for analytical method development and quality control.
The molecular framework of (4aR,9bS)-2,8-dimethyl-1H,2H,3H,4H,4aH,5H,9bH-pyrido[4,3-b]indole (C13H18N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 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.
As a certified reference material (CRM), (4aR,9bS)-2,8-dimethyl-1H,2H,3H,4H,4aH,5H,9bH-pyrido[4,3-b]indole 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.
