Descrizione generale

Folic acid, also known as pteroyl-L-glutamic acid, belongs to the vitamin B group. The conformational analysis of folic acid in the solution has been reported based on nuclear magnetic resonance (NMR) and theoretical calculations.[1] The reaction kinetics of the photodecomposition under ultraviolet radiation has been investigated.[2] This product is a high quality pharmacopoeia product that meets the testing specifications of USP (United States Pharmacopoeia). It can be employed in research and pilot studies.

Applicazioni

Folic acid has been used in a study to investigate its protective effects against the toxicity caused by valproic acid (VPA) on maternal liver tissue.[3] It has also been used as standard for the quantification of plasma folic acid by reversed-phase HPLC.[4]

Questions

1–2 of 2 Questions  
  1. 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

  2. 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.
