Chemical Structure
Description
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.
CATO supplies Methyl 2-(4-phenylbut-3-en-2-ylidene)-1-(((2-((2E,3E)-4-phenylbut-3-en-2-ylidene)hydrazine-1-carbonyl)oxy)methyl)hydrazine-1-carboxylate (CAS 358723-68-9), a certified reference material (molecular formula C24H26N4O4, MW 434.49 g/mol) for analytical method development and quality control.
Methyl 2-(4-phenylbut-3-en-2-ylidene)-1-(((2-((2E,3E)-4-phenylbut-3-en-2-ylidene)hydrazine-1-carbonyl)oxy)methyl)hydrazine-1-carboxylate (C24H26N4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
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.
