Application

Methylamine can be used as a reagent in the synthesis of the following:     
  • Methylmorpholine from diethylene glycol.[1]       
  • N-methylalkylamines from oxoamines via formation of imine, followed by hydrogenation using Ni catalyst.[1]   
  • N-Methyldipropylenetriamine by reacting with acrylonitrile, followed by hydrogenation.[1]  
  • N-methyl hydroxypyrrolidines from chlorohydrin in the presence of NaCNBH as a reducing agent.[2]       
  • 2-(Methylamino)-6,7-dichloro-1,4-anthracenedione by reacting with 6,7-dichloro-1,4-anthracenedione.[3]

Methylamine solution 2.0 M in THF can be used as a precursor that facilitates the synthesis of perovskite based materials. It can also be used as a deactivating agent to study the catalytic performance of acidic macroporous ion exchange resins. It can be annealed to reduce impurity in the grain boundaries, improve the stability and efficiency of the perovskite solar cells.[4][5][6]

General description

Methylamine (CH3NH2) is a simple aliphatic primary amine used as a chemical intermediate in organic synthesis. It is prominently used in the production of pesticides and solvents.[1][7]

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
