애플리케이션

trans-2-Butene can be used as a monomer unit to produce high molecular weight polyolefins with well-defined microstructures by nickle-catalyzed polymerization reaction. It is also used as a reactant in the isomerization reaction to produce the corresponding isomer using acid-activated catalysts.[1][2]

포장

Supplied in a Sure/Pac™ cylinder and has a brass needle valve with a male 1/4" NPTF outlet thread installed. Before using the cylinder, ensure that the valve is closed, then remove the galvanized steel hex cap that seals the outlet valve.

A cytochrome P-450 LM2 reconstituted system mediated expoxidations of small terminal alkenes to the corresponding alkyloxiranes. This oxidation was accompanied by a stereoselective proton exchange of the E proton. Propene was oxidized in D2O to trans-3-deuterio-2-methyloxirane, and E-1-deuteriopropene was epoxidized

질문

1–2 / 2 질문  

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

    1 답변

    1. 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.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 답변

    1. 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
