Description
CATO manufactures 4-Bromo-3-(4-bromophenyl)-5-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.
CATO supplies 4-Bromo-3-(4-bromophenyl)-5-methyl-1H-pyrazole (CAS 1239232-79-1), a certified reference material (molecular formula C10H12Br2N2, MW 320.02 g/mol) for analytical method development and quality control.
Structurally, 4-Bromo-3-(4-bromophenyl)-5-methyl-1H-pyrazole (C10H12Br2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 320.02 g/mol, it falls into the moderately-high-molecular-weight range. 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.
