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

2,5-Dichlorobenzo[d]thiazole features a rigid, electron-deficient heterocyclic core that integrates seamlessly into pharmaceutical and materials synthesis. The ortho-chlorine substituents enhance reactivity in electrophilic substitution while maintaining stability under standard conditions. This compound serves as a key scaffold for bioactive molecules and functional polymers.

Application

2,5-Dichlorobenzo[d]thiazole serves as a versatile building block for heterocyclic synthesis, enabling efficient construction of complex scaffolds via palladium-catalyzed cross-coupling reactions. The dichloro substitution pattern provides orthogonal reactivity for sequential functionalization, while the benzo[d]thiazole core offers enhanced stability and favorable electronic properties for medicinal chemistry applications. Its bench-stable nature and compatibility with standard synthetic protocols facilitate straightforward purification and integration into multi-step sequences.
