Chemical Structure
Description
CATO supplies (S)-2-(5-Nitro-1H-indazole-1-carboxamido)-3-phenylpropanoic acid (CAS 664985-95-9), a certified reference material (molecular formula C17H14N4O5, MW 354.32 g/mol) for analytical method development and quality control.
(S)-2-(5-Nitro-1H-indazole-1-carboxamido)-3-phenylpropanoic acid (C17H14N4O5) 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.
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.
