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

4-Fluorobenzo[d]oxazol-2(3H)-one features a fluorinated oxazole ring fused to a benzene system, delivering enhanced electron-withdrawing character and improved metabolic stability. This scaffold integrates readily into bioactive molecules, serving as a rigid, polar isostere for carboxylic acids or amides in medicinal chemistry campaigns.

Application

4-Fluorobenzo[d]oxazol-2(3H)-one serves as a versatile heterocyclic building block for medicinal chemistry and materials science. Its fluorinated aromatic core enhances metabolic stability and modulates electronic properties, while the oxazolone moiety enables facile functionalization via nucleophilic substitution or transition-metal-catalyzed coupling. The compound exhibits good bench stability and compatibility with common reaction conditions, facilitating integration into multi-step syntheses of bioactive scaffolds and functionalized polymers.
