Description

Choline is a vital, water-soluble quaternary ammonium compound that serves as a precursor for essential phospholipids and the neurotransmitter acetylcholine. Its role as a methyl donor and its involvement in cell membrane integrity and signaling make it a critical nutrient for human, animal, and plant health. This high-purity material is essential for manufacturers in the pharmaceutical, nutraceutical, animal feed, and cosmetic industries, where consistent quality and reliable supply are paramount.

Application

• Pharmaceutical & Nutraceutical Ingredients: Used in the synthesis of active pharmaceutical ingredients (APIs) and as a key component in dietary supplements for liver health, cognitive function, and fetal development.
• Animal Feed Additive: An essential nutrient added to poultry, swine, and aquaculture feed to promote growth, improve feed efficiency, and prevent metabolic disorders like fatty liver syndrome.
• Cosmetic & Personal Care: Incorporated into skincare formulations for its hydrating and skin-barrier reinforcing properties, often as choline chloride or other derivatives.
• Biochemical Research & Cell Culture: Serves as a defined component in cell culture media and as a reagent in life science research studying lipid metabolism and neurotransmission.
• Industrial Applications: Utilized as a catalyst or intermediate in certain organic synthesis processes and in the production of specialty chemicals.

Quality Control

Our choline is produced under a strict quality management system. Every batch is tested to ensure it meets stringent specifications for identity, purity, and composition. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, water content, and residual solvents. Our quality commitment supports compliance with relevant standards for pharmaceutical, food, and feed-grade applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking and degradation. Recommended long-term storage temperature is between 2°C and 8°C.
