Description

Methyl 2-Amino-3-(4-Methylphenyl)Propanoate is a specialized chiral amino acid ester derivative, serving as a critical building block in advanced organic synthesis. Its value lies in providing a protected phenylalanine analog with a methyl ester group, facilitating efficient peptide coupling and modification reactions. This compound is essential for researchers and manufacturers in the pharmaceutical and fine chemical industries, particularly for developing novel active pharmaceutical ingredients (APIs) and complex chiral molecules.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of peptide-based drugs, enzyme inhibitors, and other bioactive molecules.
• Chiral Building Block: Used in asymmetric synthesis to introduce a specific stereocenter into more complex target compounds.
• Protecting Group Strategy: The methyl ester moiety acts as a protecting group for the carboxylic acid function during multi-step synthetic sequences.
• Research & Development: Valuable tool in medicinal chemistry for structure-activity relationship (SAR) studies and lead optimization.
• Fine Chemical Synthesis: Employed in the production of specialty chemicals, flavors, and fragrances requiring specific chiral purity.

Quality Control

Our Methyl 2-Amino-3-(4-Methylphenyl)Propanoate is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for research and synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and other critical parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and handling properties.
