Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 6,11-Dihydro-5H-benzo[a]carbazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 219.28 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.
6,11-Dihydro-5H-benzo[a]carbazole (CAS 21064-49-3), molecular formula C16H13N and molecular weight 219.28 g/mol, is a CATO reference standard with documented purity and traceability.
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), 6,11-Dihydro-5H-benzo[a]carbazole 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.
