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-Chloro-5-methyl-1,3-benzoxazole is a heterocyclic scaffold featuring a chlorinated benzene ring fused to an oxazole with a methyl substituent. This electron-deficient system enables direct functionalization in cross-coupling reactions and serves as a stable building block in medicinal chemistry and agrochemical synthesis under standard conditions.

Application

2-Chloro-5-methyl-1,3-benzoxazole serves as a versatile heterocyclic building block in medicinal chemistry and materials science. Its electrophilic chlorine at the 2-position enables palladium-catalyzed cross-coupling reactions, while the methyl group provides a site for further functionalization. The benzoxazole core offers metabolic stability and favorable physicochemical properties, making it valuable in the synthesis of bioactive compounds and advanced organic materials.
