Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
7-Chloro-2,3-dihydro-1H,5H-pyrido[3,2,1-ij]quinolin-5-one (CAS 57625-59-9), molecular formula C12H10ClNO and molecular weight 219.67 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-Chloro-2,3-dihydro-1H,5H-pyrido[3,2,1-ij]quinolin-5-one (C12H10ClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 219.67 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 7-Chloro-2,3-dihydro-1H,5H-pyrido[3,2,1-ij]quinolin-5-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.
