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.

General description
- Jones reagent is a solution of chromium trioxide in aqueous sulfuric acid.
- Using acetone as a reaction solvent, the reagent is usually used for the oxidation of primary and secondary alcohols to carboxylic acids and ketones, respectively.
- The oxidation is very rapid and exothermic.
- The reagent tolerates a variety of functionalities, such as, for example, unsaturated bonds, which are rarely oxidized.
For a comprehensive review of chromium-based reagents, see "Oxidation of Alcohols to Aldehydes and Ketones" by Tojo and Fernández, Springer Berlin, 2006, 1-97.
Application
- In the oxidative cleavage of various alkenes into carboxylic acids and ketones using a catalytic amount of osmium tetroxide.
- To prepare symmetrical binaphthols by oxidative dehydrodimerization of substituted naphthols.
- To synthesize acyl-naphthols and substituted isocoumarins from 2-(4-hydroxy-but-1-ynyl)benzaldehydes.

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
