Chemical Structure
Description
The molecular framework of 1-(2-(2-Chloroethoxy)ethyl)-1h-pyrazole (C7H11ClN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
1-(2-(2-Chloroethoxy)ethyl)-1h-pyrazole (CAS 108223-75-2) is a high-purity analytical reference standard with the molecular formula C7H11ClN2O and a molecular weight of 174.63 g/mol.
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.
