Chemical Structure

N-(tert-butoxycarbonyl)-O-(tert-butyl)serine CAS 20887-86-9 chemical structure

Description

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.

CATO supplies N-(tert-butoxycarbonyl)-O-(tert-butyl)serine (CAS 20887-86-9), a certified reference material (molecular formula C12H23NO5, MW 261.31 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H23NO5, N-(tert-butoxycarbonyl)-O-(tert-butyl)serine contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 261.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
