—— Product Detail ——

Product Overview

BOC-L-Phenylalanine (N-tert-Butoxycarbonyl-L-phenylalanine) is a protected amino acid with the molecular formula C₁₄H₁₉NO₄ and molecular weight of 265.31 g/mol. This white to off-white crystalline powder is a valuable building block in peptide synthesis and pharmaceutical research. The compound features a BOC protecting group on the nitrogen atom of L-phenylalanine.

Synthetic Process

Protection: L-Phenylalanine is reacted with di-tert-butyl dicarbonate (Boc₂O) in the presence of a base to introduce the BOC protecting group

Purification: The crude product is purified by recrystallization or chromatography

Drying: The purified product is dried under vacuum

Mechanism of Action

Peptide Synthesis: The BOC group protects the amino group during peptide coupling reactions

Deprotection: The BOC group can be removed under acidic conditions (e.g., TFA) to reveal the free amine

Chiral Building Block: The L-phenylalanine scaffold provides chirality for asymmetric synthesis

Research Applications & Market Significance

Peptide Synthesis: Key building block for the preparation of phenylalanine-containing peptides

Pharmaceutical Research: Intermediate for drug discovery programs

Asymmetric Synthesis: Chiral building block for the preparation of enantiomerically pure compounds

Biochemical Research: Used in the study of protein structure and function

Quality Specifications

Purity: ≥98.0% determined by HPLC

Melting point: 84-87°C

Optical purity: ≥99.0% ee

Loss on drying: ≤0.5%

Storage: 2-8°C, sealed, protected from light

Stable for 24 months when properly stored

Packaging & Shipping

Research quantities: 5g, 25g amber glass vials

Bulk quantities: 100g, 500g amber glass bottles
