Chemical Structure
Description
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.
6,8-Dimethyl-2-(pyridin-4-yl)quinoline-4-carbonyl chloride (CAS 1203146-78-4), molecular formula C17H13ClN2OHCl and molecular weight 333.21 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6,8-Dimethyl-2-(pyridin-4-yl)quinoline-4-carbonyl chloride (C17H13ClN2OHCl) contains a steroid core, an amide group, 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 333.21 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.
As a certified reference material (CRM), 6,8-Dimethyl-2-(pyridin-4-yl)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.
