Chemical Structure

7-Chloro-8-methyl-2-pyridin-3-ylquinoline-4-carbonyl chloride hydrochloride CAS 1332529-38-0 chemical structure

Description

The occurrence of 7-Chloro-8-methyl-2-pyridin-3-ylquinoline-4-carbonyl chloride hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Chloro-8-methyl-2-pyridin-3-ylquinoline-4-carbonyl chloride hydrochloride (CAS 1332529-38-0), molecular formula C16H10Cl2N2OHCl and molecular weight 353.63 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 7-Chloro-8-methyl-2-pyridin-3-ylquinoline-4-carbonyl chloride hydrochloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 353.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 7-Chloro-8-methyl-2-pyridin-3-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.
