Chemical Structure
Description
948294-24-4 5-Chloro-8-methylquinoline-3-carboxylic acid DTXSID00589108 (CAS 948294-24-4), molecular formula C11H18ClNO2 and molecular weight 231.72 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 948294-24-4 5-Chloro-8-methylquinoline-3-carboxylic acid DTXSID00589108 (C11H18ClNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 231.72 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 948294-24-4 5-Chloro-8-methylquinoline-3-carboxylic acid DTXSID00589108 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
