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 2-(((5-Methyl-3-nitro-1h-pyrazol-1-yl)methyl)sulfonyl)acetic acid (CAS 1006442-39-2), a certified reference material (molecular formula C7H9N3O6S, MW 263.23 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, 2-(((5-Methyl-3-nitro-1h-pyrazol-1-yl)methyl)sulfonyl)acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 263.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
