Chemical Structure
Description
The occurrence of 6-Chloro-2-(4-propylphenyl)quinoline-4-carboxylic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Chloro-2-(4-propylphenyl)quinoline-4-carboxylic acid (CAS 932886-69-6), molecular formula C19H16ClNO2 and molecular weight 325.79 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6-Chloro-2-(4-propylphenyl)quinoline-4-carboxylic acid (C19H16ClNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 325.79 g/mol, it falls into the moderately-high-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).
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 6-Chloro-2-(4-propylphenyl)quinoline-4-carboxylic acid 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.
