Description

n-Benzoyl-Dl-Methionine is a chemically modified derivative of the essential amino acid methionine, where a benzoyl group protects the amino functionality. This modification is crucial for its role as a key synthetic intermediate in the production of pharmaceuticals and fine chemicals. It is primarily sought after by manufacturers in the pharmaceutical, research, and nutraceutical sectors for its utility in peptide synthesis and as a building block for active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of peptide-based drugs and other active pharmaceutical ingredients (APIs).
• Biochemical Research: Used in proteomics and metabolic studies as a protected amino acid derivative for controlled peptide synthesis.
• Nutraceutical Development: Serves as a precursor in the formulation of advanced amino acid supplements and specialized nutritional products.
• Fine Chemical Synthesis: Employed in organic synthesis for introducing the methionine moiety into complex molecules under controlled conditions.
• Cosmetic Ingredient Synthesis: Used in the production of certain peptide-based cosmetic actives for skin and hair care formulations.

Quality Control

Our n-Benzoyl-Dl-Methionine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for use in sensitive applications. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
