Description

L-Ornithinesulfate is a high-purity, stable sulfate salt of the amino acid L-Ornithine, a key intermediate in the urea cycle. This compound is essential for applications requiring a bioavailable and consistent source of ornithine, offering superior stability and handling characteristics compared to the free base form. It is primarily utilized in the pharmaceutical, nutraceutical, and research sectors for the synthesis of active pharmaceutical ingredients (APIs), metabolic health supplements, and as a critical biochemical reagent.

Application

• Pharmaceutical Intermediates: A crucial building block in the synthesis of hepatoprotective drugs, arginine supplements, and other nitrogen metabolism-related therapeutics.
• Nutraceutical & Dietary Supplements: Used in formulations aimed at supporting liver health, ammonia detoxification, athletic performance, and the urea cycle.
• Biochemical Research: Serves as a standard and reagent in metabolic pathway studies, enzyme assays, and cell culture media for investigating amino acid metabolism.
• Cosmetic Ingredients: Incorporated into skincare products for its potential role in collagen synthesis and promoting skin health.
• Animal Nutrition: Used in specialty feed additives to support metabolic function and overall animal wellness.

Quality Control

Our L-Ornithinesulfate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and nutraceutical applications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles 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 area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of moisture from the air.
