Chemical Structure

ethyl 5,7-dichloropyrazolo[1,5-a]pyrimidine-2-carboxylate CAS 1232224-62-2 chemical structure

Description

The occurrence of ethyl 5,7-dichloropyrazolo[1,5-a]pyrimidine-2-carboxylate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

ethyl 5,7-dichloropyrazolo[1,5-a]pyrimidine-2-carboxylate (CAS 1232224-62-2), molecular formula C9H15Cl2N3O2 and molecular weight 268.14 g/mol, is a CATO reference standard with documented purity and traceability.

ethyl 5,7-dichloropyrazolo[1,5-a]pyrimidine-2-carboxylate (C9H15Cl2N3O2) contains an amide group, a carboxylic acid 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 5,7-dichloropyrazolo[1,5-a]pyrimidine-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.
