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 299405-25-7 (5-Methyl-3,4-dinitro-1H-pyrazol-1-yl)acetic acid MFCD00682554 (CAS 299405-25-7), a certified reference material (molecular formula C6H6N4O6, MW 230.14 g/mol) for analytical method development and quality control.
299405-25-7 (5-Methyl-3,4-dinitro-1H-pyrazol-1-yl)acetic acid MFCD00682554 (C6H6N4O6) contains a carbohydrate-derived structure, an amide group. 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.
