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

This review provides a summary of recent approaches in developing green methods for visible-light-mediated reactions that operate under mild conditions and avoid the need for toxic transition-metal catalysts or harsh reaction conditions.
Photoredox catalysis is a powerful synthetic methodology to form challenging covalent bonds using light irradiation. It is effective for light-driven polymer and small molecule synthesis.
Effective Csp2- and Csp-hybridized coupling reactions established for catalysis, expanding to multi-step Csp3-coupling.
自由基化学在有机合成中的应用已经过充分发展且影响广泛，但常常受制于对有毒自由基引发剂的依赖。

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.
