General description

Ethylenediamine-N,N′-disuccinic acid trisodium salt (EDDS) is an aminopolycarboxylic acid (APCA), which is used as a complexing agent. It forms stable water-soluble complexes with metal ions. EDDS has a better chelating property than EDTA.[1] It can also be used as a flushing agent due to its eco-friendly characteristics and high biodegradability.[2]

Application

EDDS (chelating agent) along with natural montmorillonite (NM) can be used in the photochemical degradation process of 17β-estradiol (E2). EDDS-NM complex can also be employed as an efficient photocatalysis system for wastewater treatment.[1] Cu and Zn ions in the contaminated agricultural soil can be removed using EDDS via Cu and Zn complex formation.[2]
Ethylenediamine-N,N′-disuccinic acid trisodium salt solution has been used as a chelate to study its effect on Eucalyptus camaldulensis tree under controlled deficit irrigation (CDI) condition.[3]
powerful, readily biodegradable chelant

In this work, the photochemical degradation process of 17β-estradiol (E2) in a suspension of natural montmorillonite (NM) has been studied. The addition of the iron complexing agent ethylenediamine-N,N'-disuccinic acid (EDDS) to the suspension was investigated and compared with the system

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
