Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N-(2,5-Dimethoxyphenyl)-1-(thiophen-2-yl)cyclopentane-1-carboxamide (CAS 1049573-77-4), a certified reference material (molecular formula C18H21NO3S, MW 331.43 g/mol) for analytical method development and quality control.
The molecular framework of N-(2,5-Dimethoxyphenyl)-1-(thiophen-2-yl)cyclopentane-1-carboxamide (C18H21NO3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
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.
