Description of Vitamin B12

Cyanocobalamin is a synthetic form of vitamin B 12. Vitamin B 12 is the “generic descriptor” name for any vitamers of vitamin B 12. Because humans and animals can convert cyanocobalamin to any one of the active vitamin B 12 compounds, by definition this makes cyanocobalamin itself a form (or vitamer) of B 12.

What is Vitamin B12?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Vitamin B12 which has developed particularly rapidly in recent years. Do you know about Vitamin B12?


The official answer:Vitamin B12, also called cobalamin, is a polycyclic compound containing 3-valent cobalt, and the four reduced pyrrole rings are connected together into one large ring of goblin (similar to porphyrin), which is the only vitamin containing metal elements. Vitamin B12 is a red crystalline powder, odorless and tasteless, slightly soluble in water and ethanol, most stable under weak acid conditions at pH 4.5~5.0, decomposed in strong acid (pH<2) or alkaline solution, and can be damaged to some extent by heat. Higher plants and animals cannot manufacture vitamin B12, and all vitamin B12 in nature is synthesized by microorganisms. Vitamin B12 is the only vitamin that requires the help of an intestinal secretion (endogenous factor) to be absorbed and is involved in the production of bone marrow red blood cells, preventing pernicious anemia and preventing damage to the nerves of the brain.

What’s the application of Vitamin B12?

The prototype of the family of naturally occurring cobalt ligand compounds is called cobalamin-like. The analogs of vitamin B12 differ only in the beta-ligand of cobalt and are called cobalamin. It is almost entirely synthesized by bacteria. Dietary sources include fish, meat, liver, and dairy productsChemicalbook; plants have little or no cobalamin. The body converts it into biologically active forms, methylcobalamin, and cobalamin, which act as enzyme cofactors. Severe deficiency may lead to megaloblastic anemia and/or neurological dysfunction.

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
