Chemical Structure
Description
The occurrence of 3-(Chloromethyl)-1-methyl-1h-pyrazole dihydrochloride is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-(Chloromethyl)-1-methyl-1h-pyrazole dihydrochloride (CAS 1955498-68-6), a certified reference material (molecular formula C5H7ClN2HCl, MW 167.03 g/mol) for analytical method development and quality control.
Based on its molecular formula C5H7ClN2HCl, 3-(Chloromethyl)-1-methyl-1h-pyrazole dihydrochloride contains a nitrile group, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 167.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
