Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (5-Bromo-2-hydroxyphenyl)(1H-pyrazol-4-yl)methanone (CAS 68100-96-9), a certified reference material (molecular formula C10H7BrN2O2, MW 267.08 g/mol) for analytical method development and quality control.
(5-Bromo-2-hydroxyphenyl)(1H-pyrazol-4-yl)methanone (C10H7BrN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), (5-Bromo-2-hydroxyphenyl)(1H-pyrazol-4-yl)methanone 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.
