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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

2-Bromo-5-chlorobenzo[d]thiazole features a fused heterocyclic core bearing bromo and chloro substituents at electron-rich positions, enabling direct functionalization in cross-coupling reactions. The strategic placement of halogens facilitates palladium-catalyzed transformations, while the rigid aromatic system enhances metabolic stability and binding affinity in medicinal chemistry applications. This compound serves as a key scaffold for synthesizing bioactive molecules and advanced materials.

Application

2-Bromo-5-chlorobenzo[d]thiazole serves as a versatile building block in medicinal chemistry and materials science, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The bromine site facilitates efficient Suzuki, Stille, or Negishi coupling, while the chlorine offers stability under standard reaction conditions. Its bench-stable crystalline form simplifies handling and purification, making it well-suited for modular synthesis of complex heterocyclic scaffolds and functionalized aromatic systems.
