Description
As a certified reference material (CRM), 7-Chloro-8-methyl-2-(2-thienyl)quinoline-4-carbonyl chloride 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-8-methyl-2-(2-thienyl)quinoline-4-carbonyl chloride (CAS 1160256-79-0), molecular formula C15H9Cl2NOS and molecular weight 322.21 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-Chloro-8-methyl-2-(2-thienyl)quinoline-4-carbonyl chloride (C15H9Cl2NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 322.21 g/mol, it falls into the moderately-high-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.
