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 4-iodo-1-methyl-3-(propan-2-yl)-1H-pyrazole (CAS 1461708-27-9), a certified reference material (molecular formula C7H11IN2, MW 250.08 g/mol) for analytical method development and quality control.
Owing to a nitrile group, iodine substitution, 4-iodo-1-methyl-3-(propan-2-yl)-1H-pyrazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.08 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.
