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

Butyl 4-methylbenzenesulfonate is a bench-stable, moisture-tolerant sulfonate ester featuring a hydrophobic butyl chain and an electron-rich para-methylphenyl group. This combination enhances solubility in organic media while maintaining reactivity for nucleophilic substitution processes. The robust sulfonate moiety facilitates clean displacement reactions under mild conditions, enabling efficient functionalization in synthetic workflows.

Application

Butyl 4-methylbenzenesulfonate serves as a stable, bench-ready sulfonate ester that facilitates efficient SN2 displacement reactions. Its excellent functional group tolerance and ease of purification make it a reliable reagent for introducing butyl groups in synthetic sequences. Widely used in organic synthesis, it functions effectively in alkylation protocols and as a building block for complex molecular architectures.
