Chemical Structure

(S)-2-((tert-Butoxycarbonyl)(methyl)amino)-4-hydroxy-4-methylpentanoic acid CAS 2050909-89-0 chemical structure

Description

The molecular framework of (S)-2-((tert-Butoxycarbonyl)(methyl)amino)-4-hydroxy-4-methylpentanoic acid (C12H23NO5) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies (S)-2-((tert-Butoxycarbonyl)(methyl)amino)-4-hydroxy-4-methylpentanoic acid (CAS 2050909-89-0), a certified reference material (molecular formula C12H23NO5, MW 261.31 g/mol) for analytical method development and quality control.

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.
