Description

Dl-Citrulline CAS NO 627-77-0 is a non-essential amino acid derivative, recognized for its role in the urea cycle and as a key intermediate in nitric oxide synthesis. This compound is crucial for applications requiring a stable and bioavailable source of citrulline, offering significant value in nutritional and pharmaceutical research and development. It is primarily sought by manufacturers in the dietary supplement, nutraceutical, and pharmaceutical industries, as well as by research institutions focused on metabolic and cardiovascular health.

Application

• Dietary Supplements & Nutraceuticals: A core ingredient in sports nutrition and wellness formulations aimed at supporting nitric oxide production, vascular health, and exercise recovery.
• Pharmaceutical Intermediates: Serves as a critical building block in the synthesis of more complex active pharmaceutical ingredients (APIs) and investigational drugs.
• Biochemical Research: Used as a standard or reagent in metabolic pathway studies, particularly those investigating the urea cycle, arginine metabolism, and endothelial function.
• Cosmetic & Personal Care: Incorporated into topical formulations for its potential skin-conditioning and antioxidant properties.
• Animal Nutrition: Employed in specialty feed additives to support metabolic health and performance in livestock and companion animals.

Quality Control

Our Dl-Citrulline is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) for every lot, detailing purity, identity, and impurity profiles. While available in various grades, our standard product meets high-purity specifications suitable for research and industrial use, with the capability to align with relevant standards such as USP or FCC based on customer requirements.

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 each use to prevent absorption of atmospheric moisture, which can affect quality and stability.
