General description

m-Phenylenediamine (MPD) is an aromatic diamine. It copolymerizes with iso- or terephthaloyl chloride and 3,5-diaminobenzoic acid or 2,4-diaminobenzene sulfonic acid (or sulfonate) to afford copolyamides by low temperature solution polymerization. MPD has been reported to be formed selectively during the hydrogenation of m-dinitrobenzene in the presence of bimetallic Ni-Pt catalysts supported on carbon. Cyclic voltammetric method has been proposed to study the electrochemical copolymerization of aniline with MPD in sulfuric acid solution.

Application

m-Phenylenediamine may be used in the synthesis of the following:
  • intrinsically electrically semiconducting microparticles of semiladder poly(m-phenylenediamine-co-2-hydroxy-5-sulfonic aniline) structures
  • extraction medium based on chitosan-poly(m-phenylenediamine) (CS-PPD) Fe3O4 nanocomposite, used as sorbent for the magnetic solid-phase extraction (MSPE) of polychlorinated biphenyls
  • series of terpolymers, via chemical oxidative polymerization
  • thin film composite (TFC) membranes based polyamide
  • TFC reverse osmosis (RO) membranes

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. Does the purity of product P23954, m-Phenylendiamine, decrease substantially if it has darkened? Some batches of this product have been found to be white, and some are dark.

    In most cases, the product is entirely usable after it has turned dark. Darkening may be apparent even when small amounts of product have been exposed to moisture in the atmosphere and there is no analyzable change in product purity. However, the products should not be used if a strong odor of ammonia is detected, as this indicates product degradation.The darkening is normal, and it is due to uptake of moisture from the atmosphere over time.

  6. My question is not addressed here, how can I contact Technical Service for assistance?
