Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (|AS)-|A-[[(1,1-Dimethylethoxy)carbonyl]amino]-benzenepropanoic Acid Methyl Ester 190189-97-0 Methyl (3S)-3-Boc-amino-3-phenylpropionate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 279.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies (|AS)-|A-[[(1,1-Dimethylethoxy)carbonyl]amino]-benzenepropanoic Acid Methyl Ester 190189-97-0 Methyl (3S)-3-Boc-amino-3-phenylpropionate (CAS 190189-97-0), a certified reference material (molecular formula C15H21NO4, MW 279.33 g/mol) for analytical method development and quality control.
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.
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.
