Chemical Structure
Description
CATO supplies 4-(4-Bromo-1h-pyrazol-1-yl)-2-methyl-2-(methylamino)butanoic acid (CAS 1247052-27-2), a certified reference material (molecular formula C9H14BrN3O2, MW 276.13 g/mol) for analytical method development and quality control.
4-(4-Bromo-1h-pyrazol-1-yl)-2-methyl-2-(methylamino)butanoic acid (C9H14BrN3O2) 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 4-(4-Bromo-1h-pyrazol-1-yl)-2-methyl-2-(methylamino)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.
