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

5-Bromo-4-methyl-1,2-thiazole is a heterocyclic building block featuring a bromine substituent at the 5-position and a methyl group at the 4-position on the 1,2-thiazole scaffold. This electron-deficient ring system enables direct functionalization in cross-coupling reactions. The bromine moiety serves as a handle for palladium-catalyzed transformations, while the methyl group enhances solubility and modulates reactivity. This compound offers high stability under standard bench conditions and integrates readily into complex molecular architectures.

Application

5-Bromo-4-methyl-1,2-thiazole serves as a versatile building block for the synthesis of bioactive heterocycles and pharmaceutical intermediates. The bromine substituent enables palladium-catalyzed cross-coupling reactions, while the methyl group enhances regioselectivity in electrophilic substitution. Its bench-stable nature and compatibility with common functional groups facilitate straightforward incorporation into complex molecular architectures.
