    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-Butoxybenzenesulfonyl chloride features a butoxy-substituted aromatic ring that enhances solubility in organic media while the sulfonyl chloride group enables efficient coupling reactions. This reagent integrates readily into sulfonamide syntheses and serves as a key intermediate in the development of functionalized pharmaceuticals and agrochemicals under standard conditions.

Application

4-Butoxybenzenesulfonyl chloride serves as a versatile sulfonylating agent for the efficient introduction of sulfonate groups into aromatic and heteroaromatic systems. Its stability under standard bench conditions and compatibility with diverse functional groups facilitate clean derivatization in late-stage synthesis. The butoxy substituent enhances solubility in organic media, enabling straightforward purification and scalability in pharmaceutical and agrochemical intermediate production.
