Chemical Structure

(R)-2-((R)-2-Aminopropanamido)-4-methylpentanoic acid CAS 67392-69-2 chemical structure

Description

The occurrence of (R)-2-((R)-2-Aminopropanamido)-4-methylpentanoic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (R)-2-((R)-2-Aminopropanamido)-4-methylpentanoic acid (CAS 67392-69-2), a certified reference material (molecular formula C9H18N2O3, MW 202.25 g/mol) for analytical method development and quality control.

(R)-2-((R)-2-Aminopropanamido)-4-methylpentanoic acid (C9H18N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
