Chemical Structure

1-(2-Chloroethyl)-4-methyl-1H-pyrazole hydrochloride CAS 1820686-16-5 chemical structure

Description

Based on its molecular formula C6H9ClN2HCl, 1-(2-Chloroethyl)-4-methyl-1H-pyrazole hydrochloride contains a nitrile group, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 181.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

1-(2-Chloroethyl)-4-methyl-1H-pyrazole hydrochloride (CAS 1820686-16-5), molecular formula C6H9ClN2HCl and molecular weight 181.06 g/mol, is a CATO reference standard with documented purity and traceability.

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.
