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-Bromo-5-methylisoxazol-3-amine features a brominated isoxazole core with a methyl group at the 5-position and a primary amine at the 3-position. This electron-deficient heterocycle integrates readily into pharmaceutical scaffolds, offering high functional group tolerance and stability under standard bench conditions. The pendant amine enables direct coupling for bioconjugation or further derivatization.

Application

4-Bromo-5-methylisoxazol-3-amine serves as a versatile building block for the synthesis of bioactive heterocycles, enabling efficient access to isoxazole-based scaffolds through palladium-catalyzed cross-coupling reactions. Its bromo group facilitates C–C and C–N bond formation under standard conditions, while the pendant amine supports derivatization via acylation or alkylation. The compound exhibits good bench stability and simplifies purification in multi-step sequences, making it well-suited for medicinal chemistry and process development workflows.
