Description

Phenylalanine CAS NO 167088-01-9 is an essential aromatic amino acid, serving as a fundamental building block for proteins and a critical precursor in numerous biochemical pathways. Its high purity and consistent quality are vital for ensuring the efficacy and safety of downstream products in regulated industries. This compound is essential for manufacturers in the pharmaceutical, nutraceutical, and food and beverage sectors, where it is used in parenteral nutrition, dietary supplements, and as a flavor enhancer.

Application

• Pharmaceutical Intermediates: Key chiral building block for the synthesis of active pharmaceutical ingredients (APIs), including antiviral and neurological drugs.
• Parenteral Nutrition: A critical component in amino acid solutions for intravenous feeding, requiring the highest pharmacopeial standards (USP/EP).
• Dietary Supplements & Nutraceuticals: Used in protein powders, sports nutrition, and wellness products to support muscle protein synthesis and cognitive function.
• Food & Beverage Industry: Employed as a nutritional fortifier and as a precursor for the artificial sweetener aspartame.
• Biochemical Research: Essential reagent in cell culture media, enzyme studies, and metabolic pathway analysis.
• Cosmetic & Personal Care: Incorporated into skin-care formulations for its potential role in supporting skin barrier function.

Quality Control

Our Phenylalanine is manufactured under strict quality management systems. It can be supplied to meet various pharmacopeial standards, including USP, EP, and JP, as well as Food Chemical Codex (FCC) grade for nutritional applications. Every batch undergoes rigorous analytical testing, including chiral purity verification and heavy metal screening. A comprehensive Certificate of Analysis (COA) documenting identity, assay, impurity profile, and residual solvents is provided with each shipment to ensure full traceability and compliance.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
