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-Dichloro-1,3-thiazole is a bench-stable, electron-deficient heterocycle featuring two chlorine substituents at the 2 and 5 positions. This configuration enhances its reactivity in nucleophilic substitution processes, enabling efficient incorporation into complex molecular architectures. The molecule’s rigid, planar structure supports its use as a building block in medicinal chemistry and materials science applications.

Application

2,5-Dichloro-1,3-thiazole serves as a versatile building block in medicinal chemistry and synthetic organic chemistry, enabling efficient construction of bioactive heterocycles. Its dichloro substitution pattern enhances electrophilic reactivity at C2 and C5, facilitating nucleophilic displacement and transition-metal-catalyzed coupling reactions. The compound exhibits good bench stability and compatibility with common functional groups, making it valuable for modular synthesis of pharmaceutical intermediates and agrochemical scaffolds.
