7-Chloro-8-methyl-2-(5-methyl-2-thienyl)quinoline-4-carbonyl chloride CAS 1160256-82-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Chloro-8-methyl-2-(5-methyl-2-thienyl)quinoline-4-carbonyl chloride.

7-Chloro-8-methyl-2-(5-methyl-2-thienyl)quinoline-4-carbonyl chloride (CAS 1160256-82-5) is a high-purity analytical reference standard with the molecular formula C16H11Cl2NOS and a molecular weight of 336.24 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 7-Chloro-8-methyl-2-(5-methyl-2-thienyl)quinoline-4-carbonyl chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
