General description

Diethyl phthalate (DEP) is a phthalic anhydride ester (PAE) that is commonly used as a solvent in cosmetics and also as a plasticizer.[1]

Application

Diethyl phthalate can be used as a solvent for the antimony reduction of aluminum chloride-phosphorus trichloride-alkyl chloride complexes to form the corresponding alkylphosphonous dichlorides.[2] It can undergo condensation with o-phenylenediamine in the presence of sodium hydride to form dibenzo (b,f)(1,4)diazocine-6,11(5H, 12H)-dione.[3]

Other Notes

Plasticizer.

Questions

1–6 of 6 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/449/386/product-dating-information-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

  5. I want to use Product 524972, Diethyl phthalate in cell culture or tissue culture.  In what solvent can I dilute diethyl phthlate?

    1 answer

    1. Product 524972, Diethyl phthalate, is soluble in ethanol to 0.1 M.  Lee, S.-M., et al., Dibutyl Phthalate Biodegradation by the White Rot Fungus, Polyporus brumalis.  Biotechnology and Bioengineering, 97(6), 1516-1522 (2007).

  6. How does the storage temperature relate to shipping conditions?

    1 answer

    1. The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.
