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

Sulfisoxazole is a sulfonamide antibiotic featuring a benzene ring substituted with a sulfonamide group and a heterocyclic thiazole moiety. This structure enables effective inhibition of bacterial folate synthesis, delivering broad-spectrum activity against susceptible Gram-positive and Gram-negative organisms. The compound exhibits good solubility in aqueous media and maintains stability under standard storage conditions.

Application

Sulfisoxazole serves as a well-established sulfonamide antibiotic and key building block in medicinal chemistry, enabling the synthesis of heterocyclic scaffolds through its reactive aromatic amine and sulfonamide functionalities. Its bench-stable nature and compatibility with standard coupling protocols facilitate efficient derivatization for API development.
