Chemical Structure
Description
(E)-2-((5-nitrofuran-2-yl)methylene)hydrazine-1-carboximidamide hydrochloride (C6H7N5O3HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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).
CATO supplies (E)-2-((5-nitrofuran-2-yl)methylene)hydrazine-1-carboximidamide hydrochloride (CAS 946-48-5), a certified reference material (molecular formula C6H7N5O3HCl, MW 233.61 g/mol) for analytical method development and quality control.
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.
