Chemical Structure

3-(4-Methyl-1h-pyrazol-1-yl)propanehydrazide CAS 512809-34-6 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.

3-(4-Methyl-1h-pyrazol-1-yl)propanehydrazide (CAS 512809-34-6), molecular formula C7H12N4O and molecular weight 168.20 g/mol, is a CATO reference standard with documented purity and traceability.

3-(4-Methyl-1h-pyrazol-1-yl)propanehydrazide (C7H12N4O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; 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).

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.
