Description

Compared with other compounds in its class, the molecular weight of 264.77 g/mol gives 3,5-Dimethyl-1-(pentan-3-yl)-1h-pyrazole-4-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3,5-Dimethyl-1-(pentan-3-yl)-1h-pyrazole-4-sulfonyl chloride (CAS 1247650-98-1), a certified reference material (molecular formula C10H17ClN2O2S, MW 264.77 g/mol) for analytical method development and quality control.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 3,5-Dimethyl-1-(pentan-3-yl)-1h-pyrazole-4-sulfonyl chloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
