General description

3,4-Dichloroaniline (3,4-DCA) is an aromatic amine and is a model environmental contaminant. It is an important precursor for the synthesis and degradation product of several herbicides.[1] It is a metabolite of commonly applied herbicide, 3,4-dichloropropionanilide or propanil.[2] Biodegradation kinetics of 3,4-DCA has been reported.[1] Mechanism of degradation of aqueous 3,4-DCA in a novel dielectric barrier discharge plasma reactor has been studied. 1,2-dichlorobenzene, 2-chloro-1,4-benzoquinone, 3,4-dichlorophenyl isocyanate, 2-chlorohydroquinone, 3,4-dichloronitrobenzene and 3,4-dichlorophenol were identified as degradation intermediates by GC-MS analysis.[3]

Application

3,4-Dichloroaniline may be employed as derivatization reagent for the HPLC analysis of perfluorooctanoic acid (PFOA).[4]

A simple derivatization method followed by high performance liquid chromatography (HPLC) for the analysis of perfluorooctanoic acid (PFOA) was developed. PFOA was firstly derivatized with 3,4-dichloroaniline (DCA) using carbodiimide method. The typical amidate product was characterized by mass spectrometry (MS).

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.
      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
