Chemical Structure

Ethyl 4-chloro-8-hydroxy-2-(methylthio)thiazolo[4,5-g]quinoline-7-carboxylate CAS 70201-09-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4-chloro-8-hydroxy-2-(methylthio)thiazolo[4,5-g]quinoline-7-carboxylate.

CATO supplies Ethyl 4-chloro-8-hydroxy-2-(methylthio)thiazolo[4,5-g]quinoline-7-carboxylate (CAS 70201-09-1), a certified reference material (molecular formula C10H6ClNO3, MW 223.61 g/mol) for analytical method development and quality control.

Ethyl 4-chloro-8-hydroxy-2-(methylthio)thiazolo[4,5-g]quinoline-7-carboxylate (C10H6ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures Ethyl 4-chloro-8-hydroxy-2-(methylthio)thiazolo[4,5-g]quinoline-7-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
