Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5H-Pyrido[4,3-b]indole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 168.19 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.
CATO supplies 5H-Pyrido[4,3-b]indole (CAS 244-69-9), a certified reference material (molecular formula C11H8N2, MW 168.19 g/mol) for analytical method development and quality control.
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), 5H-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.
