8-Bromo-4-chloro-7-methylpyrazolo[1,5-a][1,3,5]triazine-2-carboxylic acid CAS 2387596-40-7 chemical structure

Description

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 supplies 8-Bromo-4-chloro-7-methylpyrazolo[1,5-a][1,3,5]triazine-2-carboxylic acid (CAS 2387596-40-7), a certified reference material (molecular formula C7H4BrClN4O2, MW 291.49 g/mol) for analytical method development and quality control.

8-Bromo-4-chloro-7-methylpyrazolo[1,5-a][1,3,5]triazine-2-carboxylic acid (C7H4BrClN4O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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.

CATO manufactures 8-Bromo-4-chloro-7-methylpyrazolo[1,5-a][1,3,5]triazine-2-carboxylic acid 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.
