Chemical Structure
Description
3-(4-Bromo-3,5-dimethyl-1h-pyrazol-1-yl)butanoic acid (CAS 890596-64-2) is a high-purity analytical reference standard with the molecular formula C9H13BrN2O2 and a molecular weight of 261.12 g/mol.
The molecular framework of 3-(4-Bromo-3,5-dimethyl-1h-pyrazol-1-yl)butanoic acid (C9H13BrN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 3-(4-Bromo-3,5-dimethyl-1h-pyrazol-1-yl)butanoic acid 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.
