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.
CATO supplies (2S,3R)-2-(5-(Tert-butoxycarbonyl)-1-methyl-3-oxo-2,5-diazaspiro[3.4]octan-2-yl)-3-hydroxybutanoic acid (CAS 1621435-39-9), a certified reference material (molecular formula C16H26N2O6, MW 342.39 g/mol) for analytical method development and quality control.
The molecular framework of (2S,3R)-2-(5-(Tert-butoxycarbonyl)-1-methyl-3-oxo-2,5-diazaspiro[3.4]octan-2-yl)-3-hydroxybutanoic acid (C16H26N2O6) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
