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-Bromo-3-methoxybenzene-1-sulfonyl chloride delivers a reactive sulfonyl chloride handle paired with electron-donating methoxy and bromo substituents. This combination enhances electrophilicity while maintaining stability under standard bench conditions, enabling efficient coupling in synthesis of sulfonamide-based pharmaceutical intermediates and functionalized aromatic systems.

Application

4-Bromo-3-methoxybenzene-1-sulfonyl chloride serves as a versatile sulfonyl chloride building block for the synthesis of sulfonamide-containing compounds. Its reactivity enables efficient coupling with amines under mild conditions, facilitating the construction of pharmaceutically relevant scaffolds. The bromo and methoxy substituents provide orthogonal functional handles for further derivatization via cross-coupling or electrophilic substitution reactions. Bench-stable and amenable to straightforward purification, it supports scalable synthesis in medicinal chemistry and process development workflows.
