Chemical Structure

5-(2-chloroethyl)-1-ethyl-1H-pyrazole hydrochloride CAS 1797036-93-1 chemical structure

Description

5-(2-chloroethyl)-1-ethyl-1H-pyrazole hydrochloride (C7H11ClN2HCl) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 5-(2-chloroethyl)-1-ethyl-1H-pyrazole hydrochloride (CAS 1797036-93-1), a certified reference material (molecular formula C7H11ClN2HCl, MW 195.09 g/mol) for analytical method development and quality control.

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.
