Description

Arginine Ethyl Ester is a high-purity derivative of the essential amino acid L-Arginine, modified with an ethyl ester group to enhance its lipophilicity and bioavailability. This modification is critical for applications requiring improved cellular membrane penetration and metabolic stability. It serves as a key synthetic intermediate and active ingredient for the pharmaceutical, nutraceutical, and advanced research sectors, where precise chemical functionality is paramount.

Application

• Pharmaceutical Intermediate: Used in the synthesis of peptide-based drugs and prodrugs designed for enhanced delivery and efficacy.
• Nutraceutical & Sports Nutrition: Incorporated into formulations targeting nitric oxide production, vascular health, and muscle performance.
• Biochemical Research: Serves as a crucial reagent in proteomics, enzyme studies, and metabolic pathway analysis.
• Cosmeceutical Actives: Employed in advanced skincare products for its potential role in collagen synthesis and skin barrier function.
• Chemical Synthesis: Acts as a protected arginine building block in organic and peptide chemistry.

Quality Control

Our Arginine Ethyl Ester is manufactured under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including HPLC for purity, chiral analysis for enantiomeric excess, and identity confirmation via IR and NMR. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to ensure traceability and compliance with your project requirements.

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 nature, the container must be kept tightly sealed after each use to prevent moisture absorption and potential degradation.
