N,5-Dimethyl-4,5-dihydro-1H-pyrazole-1-carboxamide CAS 71233-33-5

Description

The occurrence of N,5-Dimethyl-4,5-dihydro-1H-pyrazole-1-carboxamide is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N,5-Dimethyl-4,5-dihydro-1H-pyrazole-1-carboxamide (CAS 71233-33-5) is a high-purity analytical reference standard with the molecular formula C6H11N3O and a molecular weight of 141.17 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, N,5-Dimethyl-4,5-dihydro-1H-pyrazole-1-carboxamide is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
