General description
Viscosities of binary mixtures of 2-bromobutane and the isomeric forms of butanol have been evaluated at 298.15 and 313.15K. 2,2-dibromobutane, meso-2,3-dibromobutane and dl-2,3-dibromobutane are formed as major photobromination reaction products, during its reaction with molecular bromine. Smaller yields of 1,2-dibromobutane and 2,2,3-tribromobutane are also obtained in this reaction.
2-Bromobutane is an alkyl halide. Degradation of 2-bromobutane by reductive dehalogenation in the presence of nickel-aluminum alloy in potassium hydroxide solution has been reported.[1] Gas chromatographic determination of 2-bromobutane in mixture of alkyl bromides has been reported. Stereochemistry of dehydrobromination of 2-bromobutane over KOH-silica has been investigated.
Application
2-Bromobutane may be used in the synthesis of series of non-nucleosides.[2]

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
