Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ((2S,4S)-1-benzyl-4-((tert-butyldimethylsilyl)oxy)pyrrolidin-2-yl)methanol.
((2S,4S)-1-benzyl-4-((tert-butyldimethylsilyl)oxy)pyrrolidin-2-yl)methanol (CAS 635299-82-0), molecular formula C18H31NO2Si and molecular weight 321.53 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of ((2S,4S)-1-benzyl-4-((tert-butyldimethylsilyl)oxy)pyrrolidin-2-yl)methanol (C18H31NO2Si) is characterized by a steroid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures ((2S,4S)-1-benzyl-4-((tert-butyldimethylsilyl)oxy)pyrrolidin-2-yl)methanol 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.
