Frequently asked questions
What is oxalyl chloride (2.0M in dichloromethane) commonly used for in chemical synthesis?
This solution is primarily used as a reagent in Swern oxidations, converting alcohols to aldehydes or ketones under mild conditions, and for activating carboxylic acids in peptide synthesis.
What is the chemical formula and molecular weight of oxalyl chloride?
The formula is C₂Cl₂O₂, and the molecular weight is 126.93 g/mol (anhydrous). The 2.0M solution in dichloromethane includes the solvent’s contribution to the total mass.
How should oxalyl chloride (2.0M in DCM) be stored?
Store the solution in a tightly sealed container at ambient temperature, away from moisture and light, as it hydrolyzes readily in air.
What purity grades or specifications are available for this product?
Molekula supplies this as a reagent-grade solution (2.0M in dichloromethane), suitable for most synthetic applications requiring high purity.
Can Molekula supply oxalyl chloride in bulk quantities (e.g., >5L or 20L containers)?
Yes, bulk quantities are available upon request—please contact our sales team to discuss custom packaging or larger volumes.
What documentation is provided with an order of oxalyl chloride (2.0M in DCM)?
