1-Methyl-1h-pyrazole-4-sulfonohydrazide CAS 1006356-34-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 176.20 g/mol gives 1-Methyl-1h-pyrazole-4-sulfonohydrazide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Methyl-1h-pyrazole-4-sulfonohydrazide (CAS 1006356-34-8) is a high-purity analytical reference standard with the molecular formula C4H8N4O2S and a molecular weight of 176.20 g/mol.

1-Methyl-1h-pyrazole-4-sulfonohydrazide (C4H8N4O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), 1-Methyl-1h-pyrazole-4-sulfonohydrazide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
