Description
As a certified reference material (CRM), 2,7-Dichloro-3-(2-chloroethyl)-8-methylquinoline 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.
2,7-Dichloro-3-(2-chloroethyl)-8-methylquinoline (CAS 948291-91-6), molecular formula C12H10Cl3N and molecular weight 274.57 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,7-Dichloro-3-(2-chloroethyl)-8-methylquinoline (C12H10Cl3N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 274.57 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
