Allgemeine Beschreibung

Nicotinic acid is also known as vitamin B3 or Niacin. It is a water soluble vitamin. Niacin can be either synthesized within the body or can be obtained from dietary sources.[1]

Anwendung

Nicotinic acid has been used:
  • as a component of the MS vitamins stock solution[2]
  • for the detection of siderophores in Escherichia coli bacterial culture[3]
  • as a component of the holidic medium for adult Drosophila [4].

Biochem./physiol. Wirkung

Niacin is involved in the production of nicotinamide adenine dinucleotide (NAD+), which is used in the adenine triphosphate (ATP) production in mitochondrial oxidative phosphorylation.[1] It also decreases hepatic production of very-low density lipoproteins (VLDL), and apolipoprotein B (apo-B).[5] Niacin deficiency leads to pellagra.[6]

Questions

1–3 of 3 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.

  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
