HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

Oxan-4-yl 4-methylbenzenesulfonate serves as a robust, bench-stable leaving group in nucleophilic substitution reactions. The sulfonate moiety enables efficient displacement under mild conditions, while the oxan-4-yl scaffold provides solubility and compatibility with diverse reaction media. This combination facilitates reliable functionalization in complex synthesis workflows.

Application

Oxan-4-yl 4-methylbenzenesulfonate serves as a robust, bench-stable glycosyl donor for the synthesis of oligosaccharides and glycoconjugates. Its triflate-like reactivity enables efficient glycosylation under mild conditions, with high stereoselectivity in both α- and β-linkage formation. The tosyl group provides excellent leaving group ability while maintaining stability during storage and handling. Functions reliably in standard glycosylation protocols, facilitating clean reactions and straightforward purification—ideal for iterative carbohydrate assembly and medicinal chemistry applications.
