4-Bromo-1-((2-bromophenyl)sulfonyl)-1H-pyrazole CAS 957062-77-0

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-((2-bromophenyl)sulfonyl)-1H-pyrazole.

4-Bromo-1-((2-bromophenyl)sulfonyl)-1H-pyrazole (CAS 957062-77-0) is a high-purity analytical reference standard with the molecular formula C9H6Br2N2O2S and a molecular weight of 366.03 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 4-Bromo-1-((2-bromophenyl)sulfonyl)-1H-pyrazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 366.03 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.

As a certified reference material (CRM), 4-Bromo-1-((2-bromophenyl)sulfonyl)-1H-pyrazole 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.
