Chemical Structure

6-Methyl-2-(5-methyl-2-thienyl)quinoline-4-carbonyl chloride CAS 1160253-33-7 chemical structure

Description

The occurrence of 6-Methyl-2-(5-methyl-2-thienyl)quinoline-4-carbonyl chloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Methyl-2-(5-methyl-2-thienyl)quinoline-4-carbonyl chloride (CAS 1160253-33-7) is a high-purity analytical reference standard with the molecular formula C16H12ClNOS and a molecular weight of 301.79 g/mol.

Structurally, 6-Methyl-2-(5-methyl-2-thienyl)quinoline-4-carbonyl chloride (C16H12ClNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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 301.79 g/mol, it falls into the moderately-high-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
