Chemical Structure

Rel-(tert-butoxycarbonyl)-D-threonine CAS 86748-77-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 219.23 g/mol gives Rel-(tert-butoxycarbonyl)-D-threonine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Rel-(tert-butoxycarbonyl)-D-threonine (CAS 86748-77-8) is a high-purity analytical reference standard with the molecular formula C9H17NO5 and a molecular weight of 219.23 g/mol.

The molecular framework of Rel-(tert-butoxycarbonyl)-D-threonine (C9H17NO5) 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.

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.
