General description
We are committed to bringing you Greener Alternative Products, which adhere to one of the four categories of Greener Alternatives. This rare earth Lewis acid catalyst is used for Diels-Alder reactions, aldol condensations, Friedel-Crafts acylations, and carbonyl-compound transformations. Its high oxophilicity and water tolerance provide exceptional catalytic activity under greener aqueous or semi-aqueous conditions, aligning with Green Chemistry principle "Catalysis". Click here for more information.
Application
A water-tolerant Lewis acid catalyst recently used in one-pot syntheses of β-lactams, and in stereocontrolled radical and nucleophilic addition reactions. Catalyzes the synthesis of deoxypenostatin A in a novel, stereoselective, intramolecular Diels-Alder reaction.
Lewis acid catalyst used with a silylated chinchona alkaloid in an asymmetric synthesis of substituted β-lactams from an acid chloride and aryl imine. Also used to catalyze an aldehyde-ene reaction in a synthesis of the guaiane skeleton.
An important Lewis acid catalyst for a variety of synthetic reactions, including allylborations.

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

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
