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 Methyl 3-((tert-butoxycarbonyl)amino)-3-methylbutanoate (CAS 145486-69-7), a certified reference material (molecular formula C11H21NO4, MW 231.29 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Methyl 3-((tert-butoxycarbonyl)amino)-3-methylbutanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
