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

4-Amino-N-methylbenzenesulfonamide features a sulfonamide group conjugated to an electron-rich aromatic ring, enabling robust hydrogen bonding and enhanced solubility in polar solvents. The N-methyl substitution improves metabolic stability and reduces basicity compared to the parent amine, facilitating incorporation into bioactive scaffolds. This derivative serves as a key building block in medicinal chemistry for targeted kinase inhibition and antimicrobial agent development.

Application

4-Amino-N-methylbenzenesulfonamide serves as a key building block in sulfonamide-based medicinal chemistry, enabling the synthesis of diverse heterocyclic scaffolds and bioactive compounds. Its amino group facilitates nucleophilic substitution and coupling reactions, while the N-methylsulfonamide moiety offers enhanced metabolic stability and membrane permeability. The compound exhibits good bench stability and is readily purified by recrystallization, supporting its use in multi-step synthetic sequences for pharmaceutical intermediates.
