N-Methyl-2-(4-nitro-1H-pyrazol-1-yl)acetamide CAS 1339619-68-9 chemical structure

Description

The occurrence of N-Methyl-2-(4-nitro-1H-pyrazol-1-yl)acetamide is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-Methyl-2-(4-nitro-1H-pyrazol-1-yl)acetamide (CAS 1339619-68-9), molecular formula C6H8N4O3 and molecular weight 184.15 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-Methyl-2-(4-nitro-1H-pyrazol-1-yl)acetamide (C6H8N4O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 184.15 g/mol, it falls into the medium-molecular-weight range. 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.
