4-Bromo-1-methyl-3-((2,2,2-trifluoroethoxy)methyl)-1H-pyrazole CAS 1856025-91-6 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 4-Bromo-1-methyl-3-((2,2,2-trifluoroethoxy)methyl)-1H-pyrazole.

4-Bromo-1-methyl-3-((2,2,2-trifluoroethoxy)methyl)-1H-pyrazole (CAS 1856025-91-6), molecular formula C7H8BrF3N2O and molecular weight 273.05 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, 4-Bromo-1-methyl-3-((2,2,2-trifluoroethoxy)methyl)-1H-pyrazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 4-Bromo-1-methyl-3-((2,2,2-trifluoroethoxy)methyl)-1H-pyrazole 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.
