Description
As a certified reference material (CRM), 7-Chloro-2-methyl-3,4-dihydro-1H-benzo[c]azepin-5(2H)-one 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.
7-Chloro-2-methyl-3,4-dihydro-1H-benzo[c]azepin-5(2H)-one (CAS 1503365-73-8) is a high-purity analytical reference standard with the molecular formula C11H12ClNO and a molecular weight of 209.67 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 7-Chloro-2-methyl-3,4-dihydro-1H-benzo[c]azepin-5(2H)-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 209.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
