Chemical Structure

Ethyl 3,5-dibromo-1-methyl-1H-pyrazole-4-carboxylate, 97% CAS 1017802-88-8 chemical structure

Description

As a certified reference material (CRM), Ethyl 3,5-dibromo-1-methyl-1H-pyrazole-4-carboxylate, 97% meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies Ethyl 3,5-dibromo-1-methyl-1H-pyrazole-4-carboxylate, 97% (CAS 1017802-88-8), a certified reference material (molecular formula C7H8Br2N2O2, MW 311.96 g/mol) for analytical method development and quality control.

Ethyl 3,5-dibromo-1-methyl-1H-pyrazole-4-carboxylate, 97% (C7H8Br2N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
