Chemical Structure
Description
The occurrence of 1-Methyl-1H-pyrazole 1-methylpyrazole 930-36-9 CHEBI:59025 N-methylpyrazole is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-Methyl-1H-pyrazole 1-methylpyrazole 930-36-9 CHEBI:59025 N-methylpyrazole (CAS 930-36-9), a certified reference material (molecular formula C4H10N2, MW 86.14 g/mol) for analytical method development and quality control.
The molecular framework of 1-Methyl-1H-pyrazole 1-methylpyrazole 930-36-9 CHEBI:59025 N-methylpyrazole (C4H10N2) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
