General description

Aniline is an aromatic amine. It is a key industrial intermediate, widely employed for the preparation of dyes, rubber, resins and polymers. Complete vibrational assignements of aniline and its deuterated forms (aniline-NHD and aniline-ND2) have been reported.1 p-aminodiphenylamine (ADPA) has been reported to be formed as a major intermediate during the electropolymerizatrion of aniline. Its viscosity has been reported to be 3.1457cp at 30°C. Quantitative transformation of nitrobenzene to aniline has been carried out by employing functionalized plasmonic Au/TiO2 photocatalyst along with a Ag co-catalyst. Aniline can be prepared from nitrobenzene, via hydrogenation in the presence of Cu, Ni, Pt, Pd and Au (catalyst). It can also be prepared by photocatalytic reduction of nitrobenzene in the presence of WO3-Ag hybrid nanowires.
Material darkens in storage to reddish-brown with no loss in purity.

Application

Aniline may be used in the preparation of azobenzene.

Biochem/physiol Actions

The acute toxicity of aniline involves its activation in vivo to 4-hydroxyaniline and the formation of adducts with hemoglobin. In erythrocytes, this is associated with the release of iron and the accumulation of methemoglobin and the development of hemolytic anemia and inflammation of the spleen. Tumor formation is often observed in the spleen on prolonged administration.

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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-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
