Vitamin B12 (Cyanocobalamin) Single Component Lyophilized Powder API

Product Overview Cyanocobalamin is the stable crystalline form of vitamin B12, with exclusive CAS Number: 68-19-9. This product is high-purity single-component sterile lyophilized powder without any auxiliary materials, fillers or anti-caking agents added during production. It serves as an essential coenzyme substance participating in intracellular amino acid metabolism, fatty acid oxidation and nucleic acid synthesis, and can regulate cell proliferation, hematopoietic cell differentiation and nerve cell metabolic balance. It is widely adopted in cell culture medium preparation, nutritional intervention experiments, energy metabolism pathway research and hematology-related mechanism studies. Manufactured with standardized GMP-grade vacuum low-temperature freeze-drying technology, the product avoids molecular structural damage caused by high-temperature processing. It features ultra-low endotoxin index, outstanding water solubility, can be fully dissolved without insoluble residues or flocculent sediments. It maintains excellent compatibility with purified water, 0.9% benzyl alcohol bacteriostatic water, 0.6% acetic acid aqueous solution and other conventional reconstitution solvents for peptides and cell experiments, fully meeting the preparation standards of experimental working solutions and complete culture medium. Basic Core Parameters CAS Number: 68-19-9
