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 (2S,4S)-1-tert-Butyl 2-ethyl 4-hydroxypyrrolidine-1,2-dicarboxylate (CAS 440678-63-7), a certified reference material (molecular formula C12H20NO5, MW 258.29 g/mol) for analytical method development and quality control.
The molecular framework of (2S,4S)-1-tert-Butyl 2-ethyl 4-hydroxypyrrolidine-1,2-dicarboxylate (C12H20NO5) 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 the protonation state of its nitrogen-containing groups, 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.
CATO manufactures (2S,4S)-1-tert-Butyl 2-ethyl 4-hydroxypyrrolidine-1,2-dicarboxylate 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.
