General description

Cyanocobalamin (B12) is a water soluble vitamin, which is mainly found in animal products, like dairy products, meat and eggs. It belongs to the B12 class of vitamins, commonly called as cobalamins. Cyanocobalamin consists of four pyrrole rings with a central cobalt atom coordinated by four equatorial nitrogen ligands.[1]

Application

Required for growth, genetic stability and survival of cells in vitro. Functions to support one-carbon metabolism. Present in many classical and serum-free formulations.
Cyanocobalamin has been used to study its effects on the prevention of colon cancer.

Biochem/physiol Actions

Cyanocobalamin is used in the preparation of multivitamin supplements and fortified food. It acts as a coenzyme to convert L-methylmalonyl CoA to succinyl CoA, which is catalyzed by isomerase.[1] Cyanocobalamin is used to treat vitamin B12 deficiency. Cyanocobalamin meets USP testing specifications.

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
