Chemical Structure

3-Amino-N-methyl-1H-pyrazole-4-carboxamide CAS 77937-05-4 chemical structure

Description

3-Amino-N-methyl-1H-pyrazole-4-carboxamide (C5H8N4O) contains an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

3-Amino-N-methyl-1H-pyrazole-4-carboxamide (CAS 77937-05-4) is a high-purity analytical reference standard with the molecular formula C5H8N4O and a molecular weight of 140.14 g/mol.

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.
