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.

Type	HazMat Fee

FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

Potassium 3-(phenylsulfonyl)benzenesulfonate features a rigid, electron-deficient aromatic core with dual sulfonate groups enabling strong solubility and stability in aqueous media. This robust anion integrates readily into polar reaction systems, serving as a reliable counterion in catalytic processes requiring high ionic strength and thermal resilience under standard conditions.

Application

Potassium 3-(phenylsulfonyl)benzenesulfonate serves as a stable, bench-friendly sulfonate source enabling efficient sulfonation and cross-coupling transformations. Its dual sulfonate functionality offers orthogonal reactivity in complex molecule synthesis, facilitating late-stage derivatization and heterocycle construction with high functional group tolerance. The potassium counterion enhances solubility and simplifies purification in aqueous workups, making it well-suited for scalable synthetic workflows.
