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.

Aplicación
- La síntesis peptídica en fase sólida.
- Las reacciones de sialilación.
- La síntesis de nanopartículas de cobre mediante la reducción de la sal de nitrato de cobre utilizando NaBH4. Durante la preparación, el ACN actúa como disolvente protector, que evita la oxidación de las nanopartículas.
- La preparación de selenuros de diarilo por reacción de acoplamiento catalizada por Cu entre yoduros de arilo y diselenuro de difenilo. En este proceso, el ACN también funciona como ligando para que el catalizador de cobre aumente su actividad catalítica.

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
