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.

Application
- Carbon Dioxide Reduction to Methylamines under Metal‐Free Conditions: Reports the use of metal-free catalysts for the methylation of amines with CO2, contributing to greener chemical processes and enhancing the synthesis of methylamines (Blondiaux et al., 2014).
- Methylamine‐Gas‐Induced Defect‐Healing Behavior of CH3NH3PbI3 Thin Films for Perovskite Solar Cells: Exploration of room-temperature, ultrafast methylamine-induced defect-healing that enhances the electronic properties and efficiency of perovskite solar cells (Zhou et al., 2015).
- Thermally induced recrystallization of MAPbI3 perovskite under methylamine atmosphere: Describes a method for fabricating perovskite with large uniform crystalline grains using a methylamine atmosphere, improving the stability and efficiency of the material (Jacobs and Zang, 2016).

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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
