General description

Citric acid trisodium salt corresponds to a molecular weight of 258 Da. It has high sodium content and sieving coefficients.[1]

Application

Citric acid trisodium salt has been used:
  • as a component of mobile phase buffer in high performance liquid chromatography analysis of dorsal striatum homogenates(124)
  • as an electrolyte for NiW co-deposition(125)
  • as a component of saline-sodium citrate (SSC) buffer for wash steps in probe hybridization(126)

Biochem/physiol Actions

Citric acid trisodium salt as a 4% solution is used commercially as an anticoagulant during blood storage. It is used in continuous renal replacement therapy (CRRT) as an regional citrate anticoagulation (RCA) agent.[2] Citric acid trisodium salt is used as an electrostatic stabilizer for the generation of iron (II, III) oxide hollow microspheres nanoparticle.[3]

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.

  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
