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 (5-Bromo-2-hydroxyphenyl)(1-phenyl-1H-pyrazol-4-yl)methanone.
(5-Bromo-2-hydroxyphenyl)(1-phenyl-1H-pyrazol-4-yl)methanone (CAS 68287-72-9) is a high-purity analytical reference standard with the molecular formula C16H11BrN2O2 and a molecular weight of 343.17 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, (5-Bromo-2-hydroxyphenyl)(1-phenyl-1H-pyrazol-4-yl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 343.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 (5-Bromo-2-hydroxyphenyl)(1-phenyl-1H-pyrazol-4-yl)methanone 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.
