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.

Description générale
Application
- Combustion Properties Analysis: A detailed study on the combustion properties of a gasoline-like blend of pentene isomers, including 2-Methyl-1-butene, provided insights into laminar flame speed, ignition delay time, and CO laser absorption, aiding in the optimization of fuel formulations for enhanced engine performance (Gregoire et al., 2023).
- Hydrogenation Mechanism Study: Research utilizing the parahydrogen-induced polarization technique explored the mechanisms of methylenecyclobutane hydrogenation over supported metal catalysts, with 2-Methyl-1-butene serving as a key intermediate, offering potential advancements in catalytic process development (Salnikov et al., 2022).
- Reaction Kinetics with Hydrogen Atoms: An extensive theoretical study examined the reactions of hydrogen atoms with small alkenes, including 2-Methyl-1-butene, shedding light on the hierarchical reaction mechanisms crucial for understanding and designing better chemical synthesis processes (Power et al., 2021).
- Ozonolysis of Asymmetric Alkenes: A study on the ozonolysis of asymmetric alkenes, including 2-Methyl-1-butene, used matrix isolation and FT-IR spectroscopy to investigate the chemical pathways, providing valuable insights into atmospheric chemistry and pollutant degradation (Wang et al., 2020).

How is shipping temperature determined? And how is it related to the product storage temperature?
1 réponse-
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
