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 (E)-4-Ethoxy-4-cyclopentylamino-1,1,1-trifluorobut-3-en-2-one.
CATO supplies (E)-4-Ethoxy-4-cyclopentylamino-1,1,1-trifluorobut-3-en-2-one (CAS 1365994-86-0), a certified reference material (molecular formula C11H16F3NO2, MW 251.25 g/mol) for analytical method development and quality control.
The molecular framework of (E)-4-Ethoxy-4-cyclopentylamino-1,1,1-trifluorobut-3-en-2-one (C11H16F3NO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.
