Description

Choline is a vital, water-soluble nutrient essential for cell membrane integrity, neurotransmission, and lipid metabolism. As a key biochemical precursor, it is fundamental in the synthesis of the neurotransmitter acetylcholine and the phospholipid phosphatidylcholine. This high-purity material is critical for manufacturers in the pharmaceutical, nutraceutical, and animal feed industries, where it serves as a direct ingredient or a crucial intermediate in specialized formulations.

Application

• Pharmaceutical Synthesis: A key raw material and intermediate in the production of acetylcholine and various cholinergic drugs.
• Dietary Supplements & Infant Formula: Used as a nutritional fortifier in vitamin B-complex supplements and as a mandatory nutrient in infant formula to support brain development.
• Animal Feed Additive: Incorporated into poultry, swine, and aquaculture feed to promote growth, improve feed efficiency, and prevent metabolic disorders like fatty liver syndrome.
• Cosmetic & Personal Care: Employed in hair and skin care products for its moisturizing and conditioning properties.
• Biochemical Research: Serves as a standard and reagent in cell culture media and metabolic pathway studies.
• Industrial Applications: Used as a catalyst or intermediate in certain organic synthesis processes and in the production of specialty chemicals.

Quality Control

Our Choline is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and potency. We can supply material compliant with relevant standards such as FCC for food and nutritional applications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and 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 atmospheric moisture, which can lead to caking or degradation.
