Chemical Structure
Description
The occurrence of 4-Bromo-N'-(2-(3-methyl-5-(trifluoromethyl)-1H-pyrazol-1-yl)thiazole-4-carbonyl)benzenesulfonohydrazide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-N'-(2-(3-methyl-5-(trifluoromethyl)-1H-pyrazol-1-yl)thiazole-4-carbonyl)benzenesulfonohydrazide (CAS 956961-83-4) is a high-purity analytical reference standard with the molecular formula C15H11BrF3N5O3S2 and a molecular weight of 510.31 g/mol.
4-Bromo-N'-(2-(3-methyl-5-(trifluoromethyl)-1H-pyrazol-1-yl)thiazole-4-carbonyl)benzenesulfonohydrazide (C15H11BrF3N5O3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
