Chemical Structure

Ethyl 5-chlorothiazolo[5,4-b]pyridine-2-carboxylate CAS 1202075-71-5 chemical structure

Description

The occurrence of Ethyl 5-chlorothiazolo[5,4-b]pyridine-2-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 5-chlorothiazolo[5,4-b]pyridine-2-carboxylate (CAS 1202075-71-5) is a high-purity analytical reference standard with the molecular formula C9H7ClN2O2S and a molecular weight of 242.68 g/mol.

Ethyl 5-chlorothiazolo[5,4-b]pyridine-2-carboxylate (C9H7ClN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.

CATO manufactures Ethyl 5-chlorothiazolo[5,4-b]pyridine-2-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.
