Chemical Structure
Description
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.
tert-Butyl ((R)-1-((S)-2-amino-3-methylbutanoyl)pyrrolidin-3-yl)(ethyl)carbamate (CAS 1401666-89-4), molecular formula C16H31N3O3 and molecular weight 313.44 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl ((R)-1-((S)-2-amino-3-methylbutanoyl)pyrrolidin-3-yl)(ethyl)carbamate (C16H31N3O3) is characterized by an amide group, a carboxylic acid 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 tert-Butyl ((R)-1-((S)-2-amino-3-methylbutanoyl)pyrrolidin-3-yl)(ethyl)carbamate 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.
