Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Chlorophenyl)-3-(ethylsulfonyl)-1H-pyrrole.
2-(3-Chlorophenyl)-3-(ethylsulfonyl)-1H-pyrrole (CAS 1708179-19-4) is a high-purity analytical reference standard with the molecular formula C12H12ClNO2S and a molecular weight of 269.75 g/mol.
The molecular framework of 2-(3-Chlorophenyl)-3-(ethylsulfonyl)-1H-pyrrole (C12H12ClNO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
