Description

L-Alanine-3,3,3-D3-n-T-Boc is a deuterium-labeled, tert-butoxycarbonyl (Boc)-protected derivative of the essential amino acid L-alanine. This compound is a critical building block in advanced research, particularly for the synthesis of isotopically labeled peptides and proteins for use as internal standards in mass spectrometry. It is primarily utilized by pharmaceutical R&D laboratories, contract research organizations (CROs), and academic institutions engaged in proteomics, pharmacokinetics, and metabolic studies. The Boc protecting group offers orthogonal deprotection strategies, making it a versatile intermediate in complex solid-phase and solution-phase peptide synthesis.

Application

• Mass Spectrometry Internal Standards: Used as a stable isotope-labeled precursor for synthesizing quantitative peptide and protein standards for LC-MS/MS analysis.
• Proteomics Research: Enables the study of protein dynamics, turnover, and quantification in complex biological samples.
• Metabolic Pathway Tracing: Incorporates deuterium labels to track the fate and incorporation of alanine in metabolic flux studies.
• Pharmaceutical Development: Serves as a key intermediate in the synthesis of deuterated drug candidates for improved metabolic stability and ADME studies.
• Peptide Synthesis: A protected amino acid building block for the controlled synthesis of custom peptides, where the Boc group can be selectively removed under acidic conditions.
• NMR Spectroscopy: The deuterium labels simplify NMR spectra, aiding in structural elucidation and dynamics studies of biomolecules.
