Chemical Structure
Description
CATO supplies 2-Chloro-1-{1-[2-(3,4-dimethoxyphenyl)ethyl]-2,5-dimethyl-1h-pyrrol-3-yl}ethan-1-one (CAS 610274-31-2), a certified reference material (molecular formula C18H22ClNO3, MW 335.83 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloro-1-{1-[2-(3,4-dimethoxyphenyl)ethyl]-2,5-dimethyl-1h-pyrrol-3-yl}ethan-1-one (C18H22ClNO3) is characterized by a steroid core, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
