Chemical Structure

(2S,3R)-tert-Butyl 2-amino-3-(tert-butoxy)butanoate hydrochloride CAS 49762-58-5 chemical structure

Description

CATO manufactures (2S,3R)-tert-Butyl 2-amino-3-(tert-butoxy)butanoate hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

(2S,3R)-tert-Butyl 2-amino-3-(tert-butoxy)butanoate hydrochloride (CAS 49762-58-5) is a high-purity analytical reference standard with the molecular formula C12H25NO3HCl and a molecular weight of 267.79 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, (2S,3R)-tert-Butyl 2-amino-3-(tert-butoxy)butanoate hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
