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

N,N-Dimethylpyridin-4-amine 4-methylbenzenesulfonate is a bench-stable, moisture-tolerant catalyst salt featuring a pyridine nitrogen and a sulfonate counterion. This combination enhances solubility in polar organic solvents while maintaining high reactivity in nucleophilic substitution and coupling reactions. The dimethylamino group provides strong electron donation, accelerating catalytic processes under mild conditions.

Application

N,N-Dimethylpyridin-4-amine 4-methylbenzenesulfonate serves as a highly effective catalyst in nucleophilic substitution and coupling reactions, particularly in amine-mediated processes. Its bench-stable, crystalline form enables straightforward handling and purification. The sulfonate counterion enhances solubility in organic media while maintaining high catalytic activity. This salt functions reliably in diverse synthetic workflows, including C–N bond formation and esterification, offering consistent performance across scale-up applications.
