Chemical Structure
Description
6-Methyl-2-pyridin-2-ylquinoline-4-carbonyl-chloride hydrochloride (CAS 1332529-05-1), molecular formula C16H11ClN2OHCl and molecular weight 319.19 g/mol, is a CATO reference standard with documented purity and traceability.
6-Methyl-2-pyridin-2-ylquinoline-4-carbonyl-chloride hydrochloride (C16H11ClN2OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 6-Methyl-2-pyridin-2-ylquinoline-4-carbonyl-chloride hydrochloride 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.
