Descripción general

Methylamine solution is a 33wt.% solution of methylamine in absolute ethanol. Methylamine is an aliphatic primary amine.[1] It participates in the synthesis of isothiazolium salts.[2] Chemical degradation of methylamine solution of γ-irradiated poly(ε-caprolactone) has been described.[3] Maillard reaction of D-glucose and methylamine in aqueous acetic acid has been reported.[4]
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Aplicación

Methylamine solution in absolute ethanol 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.[5][6][7]

Preguntas

1–2 de 2 Preguntas  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 respuesta

    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.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 respuesta

    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
