Description
CATO manufactures (4S)-5-Ethoxy-4-((R)-1-methylpyrrolidin-2-yl)dihydrofuran-2(3H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies (4S)-5-Ethoxy-4-((R)-1-methylpyrrolidin-2-yl)dihydrofuran-2(3H)-one (CAS 375348-90-6), a certified reference material (molecular formula C11H19NO3, MW 213.27 g/mol) for analytical method development and quality control.
The molecular framework of (4S)-5-Ethoxy-4-((R)-1-methylpyrrolidin-2-yl)dihydrofuran-2(3H)-one (C11H19NO3) is characterized by an amino-acid-derived structure, an amide 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
