5-Methyl-4,5-dihydropyrazolo[3,4-e][1,2,4]thiadiazin-3(2H)-one 1,1-dioxide CAS 1708401-57-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methyl-4,5-dihydropyrazolo[3,4-e][1,2,4]thiadiazin-3(2H)-one 1,1-dioxide.

CATO supplies 5-Methyl-4,5-dihydropyrazolo[3,4-e][1,2,4]thiadiazin-3(2H)-one 1,1-dioxide (CAS 1708401-57-3), a certified reference material (molecular formula C5H6N4O3S, MW 202.19 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H6N4O3S, 5-Methyl-4,5-dihydropyrazolo[3,4-e][1,2,4]thiadiazin-3(2H)-one 1,1-dioxide contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 202.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
