Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 268.50 g/mol gives 100032-79-9 (4-Bromo-2-nitrophenyl)hydrazine--hydrogen chloride (1/1) DTXSID30657187 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 100032-79-9 (4-Bromo-2-nitrophenyl)hydrazine--hydrogen chloride (1/1) DTXSID30657187 (CAS 100032-79-9), a certified reference material (molecular formula C6H6BrN3O2HCl, MW 268.50 g/mol) for analytical method development and quality control.
100032-79-9 (4-Bromo-2-nitrophenyl)hydrazine--hydrogen chloride (1/1) DTXSID30657187 (C6H6BrN3O2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
