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

3-Phenylisoxazol-5-amine features a fused isoxazole ring bearing a pendant phenyl group and a primary amine at the 5-position. This scaffold integrates electron-rich aromaticity with a reactive amine handle, enabling direct coupling in amide bond formation or conjugation workflows. The molecule exhibits robust stability under standard bench conditions and displays favorable solubility in common organic solvents.

Application

3-Phenylisoxazol-5-amine serves as a versatile heterocyclic building block in medicinal chemistry, enabling efficient access to isoxazole-based scaffolds. Its amine functionality facilitates straightforward derivatization via acylation, alkylation, and coupling reactions. The compound exhibits good bench stability and functional group tolerance, making it well-suited for modular synthesis workflows. It functions as a key intermediate in the construction of bioactive molecules, particularly those requiring polar, nitrogen-rich heterocycles with defined spatial orientation.
