Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Methoxy-1,4-dimethyl-9H-carbazole-3-carbaldehyde (CAS 18073-15-9), molecular formula C16H15NO2 and molecular weight 253.30 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6-Methoxy-1,4-dimethyl-9H-carbazole-3-carbaldehyde (C16H15NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 253.30 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 6-Methoxy-1,4-dimethyl-9H-carbazole-3-carbaldehyde 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.
