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

Description

Potassium 2,5-dihydroxybenzenesulfonate features two hydroxyl groups positioned ortho to a sulfonate moiety, enabling strong coordination with metal ions. This structure imparts high solubility in aqueous media and enhances stability under physiological conditions. The compound serves as a robust chelating agent in analytical and biochemical applications.

Application

Potassium 2,5-dihydroxybenzenesulfonate serves as a stable, water-soluble scaffold for ortho-dihydroxybenzene derivatives, enabling efficient functionalization in synthetic routes to bioactive molecules. Its dual hydroxyl groups facilitate metal chelation and oxidative coupling reactions, while the sulfonate moiety enhances solubility and simplifies purification. This compound functions as a versatile building block in the synthesis of heterocyclic systems and pharmaceutical intermediates.
