Chemical Structure

N-Boc-(2S,3S)-2-hydroxy-3-amino-5-methylhexanoic acid CAS 73397-27-0 chemical structure

Description

CATO supplies N-Boc-(2S,3S)-2-hydroxy-3-amino-5-methylhexanoic acid (CAS 73397-27-0), a certified reference material (molecular formula C12H23NO5, MW 261.31 g/mol) for analytical method development and quality control.

N-Boc-(2S,3S)-2-hydroxy-3-amino-5-methylhexanoic acid (C12H23NO5) 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.

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

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.
