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-Chlorobenzo[d]isothiazole 1,1-dioxide features a fused heterocyclic core with a sulfone group enhancing electronic polarization and stability. This electron-deficient scaffold integrates readily into synthetic sequences requiring strong acceptor character. The chlorine substituent provides a handle for downstream functionalization via nucleophilic substitution or cross-coupling reactions. Bench-stable and moisture-tolerant, it serves as a robust building block in medicinal chemistry and materials synthesis.

Application

3-Chlorobenzo[d]isothiazole 1,1-dioxide serves as a versatile heterocyclic building block in medicinal chemistry, enabling the construction of bioactive scaffolds through well-established coupling reactions. Its electron-deficient isothiazole core facilitates nucleophilic substitution and transition-metal-catalyzed transformations, while the sulfonamide-like dioxide group enhances solubility and metabolic stability. Bench-stable and compatible with diverse functional groups, it functions reliably in multi-step synthesis and process development workflows.
