General description
Oxalyl chloride is a commonly used chlorinating reagent that can be prepared by the reaction of oxalic acid and phosphorus pentachloride.
Application
Oxalyl chloride may be used in the following processes:
- Preparation of Mosher′s acid chloride by reacting with Mosher′s acid in the presence of DMF.
- Activation of dimethyl sulfoxide for use in the oxidation of long-chain alcohols to carbonyls.
- Activation of α-keto carboxylic acids and N-heterocyclic carboxylic acids for alkynylation to form ynediones and N-heterocyclic ynones, respectively.
Reactant involved in:
- Synthesis of N-heterocyclic ynones and ynediones, used to activate carboxylic acids
- Chlorination and halogenation
- Three-component [3+2] cycloadditions
- Reactions with organostannanes
- Synthesis of cyclopentenones
- Carbonylations, used as a carbonyl synthon
Suitable for the synthesis of acid chlorides used to produce liquid crystals.
Packaging
The 5g, 25g and 100g units sold in the US are packaged in ampules.

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
