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

General description
Application
- 1,2-Azidoalcohols and 1,2-azidoamines via cerium(III) chloride assisted ring opening of epoxides and aziridines by sodium azide.[3]
- Cyano-bearing indolinones by oxidative arylalkylation of olefins in the presence of palladium catalyst.[4]
It may also be used as a reactant to synthesize:
- Bis (diphenylphosphino) acetonitrile by reacting with n-butyllithium and then with chlorodiphenylphosphine.[5]
- β-Acetamido ketones via coupling reaction with ketones or ketoesters and aldehydes in the presence of cobalt(II) chloride.[6]

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.

Hi! By which method is the acetonitrile dried? Is molecular sieve used? Thanks!
1 answer-
Unfortunately, the manufacturing process of this product is proprietary. If necessary, molecular sieves can help to further dry the product before use.

Hey, my name is Mohammad. We tried to develop sensor ro detect heavy metals. And I fond some peaks in the solution when I added acn 99.8% and I want to know if there is heavy metals and which metals?
1 answer-
Unfortunately, this product is not tested for heavy metals. Should this be a critical issue for the specific application, see product 900667. This product is tested for trace metals and may be a better option. See the link below to review a sample Certificate of Analysis:
