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

3-Methyl-2-(methylsulfonamido)benzoic acid features a benzene ring bearing a methyl group, a sulfonamide moiety, and a carboxylic acid functional group in ortho relationship. This arrangement imparts distinct polarity and hydrogen-bonding capacity, enabling integration into bioactive scaffolds. The molecule exhibits bench-stable handling characteristics and serves as a key intermediate for medicinal chemistry campaigns targeting kinase inhibitors and enzyme modulators.

Application

3-Methyl-2-(methylsulfonamido)benzoic acid serves as a versatile building block for medicinal chemistry and API synthesis, offering a readily functionalized aromatic core with orthogonal reactivity. The carboxylic acid group enables amide coupling and esterification, while the methylsulfonamido moiety provides a polar, hydrogen-bonding handle compatible with diverse downstream transformations. Bench-stable and amenable to standard purification methods, it facilitates efficient access to bioactive heterocycles and drug candidates through established synthetic protocols.
