SLBIO CAS 68-19-9 Vitamin Supplement Vitamin B12 Powder 1% Cyanocobalamin Powder
What is Vitamin B12?
Vitamin B12 is a polycyclic aromatic hydrocarbon containing trivalent cobalt, and is the only vitamin containing a metallic element. It is a red crystalline powder, odorless and tasteless, soluble in water, sparingly soluble in ethanol, chloroform. It is most stable under weakly acidic conditions (pH 4.5–5.0), decomposes in strong acids (pH < 2) or alkaline solutions, and is partially destroyed by heat. Higher plants and animals cannot produce vitamin B12; all vitamin B12 in nature is synthesized by microorganisms. Vitamin B12 is unique in that it requires a secretion from gastric parietal cells (endogenous factor) for absorption. It participates in the production of red blood cells in bone marrow, preventing pernicious anemia and protecting brain nerves from damage.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
