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

2-Chloro-5-methylpyridine-3-sulfonyl chloride features a reactive sulfonyl chloride group flanked by electron-withdrawing chlorine and methyl-substituted pyridine moieties. This configuration enhances electrophilicity for efficient coupling reactions in synthetic medicinal chemistry, enabling direct incorporation into pharmaceutical intermediates under mild conditions.

Application

2-Chloro-5-methylpyridine-3-sulfonyl chloride serves as a versatile sulfonyl chloride building block for the construction of sulfonamide-containing heterocycles. Its reactivity is well-established in amide and sulfonamide formation, enabling efficient functionalization under mild conditions. The pyridine core provides stability and orthogonal reactivity, while the methyl group enhances solubility and influences electronic properties. Ideal for medicinal chemistry campaigns requiring targeted sulfonamide incorporation, it facilitates straightforward purification and scale-up compatibility.
