(S)-2-((S)-2-((S)-2-Amino-3-(phosphonooxy)propanamido)-3-methylbutanamido)propanoic acid CAS 88169-77-1

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies (S)-2-((S)-2-((S)-2-Amino-3-(phosphonooxy)propanamido)-3-methylbutanamido)propanoic acid (CAS 88169-77-1), a certified reference material (molecular formula C11H22N3O8P, MW 355.28 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H22N3O8P, (S)-2-((S)-2-((S)-2-Amino-3-(phosphonooxy)propanamido)-3-methylbutanamido)propanoic acid contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 355.28 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.

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.
