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

3,5-Dichlorobenzo[d]isoxazole is a bench-stable heterocyclic scaffold featuring two chlorine substituents at the 3- and 5-positions of the benzo ring. This electron-deficient isoxazole integrates readily into synthetic routes requiring halogenated aromatic platforms. The molecule's stability under standard conditions enables straightforward handling and incorporation into diverse molecular architectures.

Application

3,5-Dichlorobenzo[d]isoxazole serves as a versatile heterocyclic building block in medicinal chemistry, enabling the construction of bioactive scaffolds through electrophilic substitution and transition-metal-catalyzed coupling reactions. Its chlorine substituents provide orthogonal reactivity for late-stage functionalization, while the isoxazole core offers metabolic stability and favorable pharmacophore properties. The compound exhibits excellent bench stability and ease of purification, facilitating integration into multi-step synthetic sequences for API development.
