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

6-Bromo-5-methyl-2H-benzo[b][1,4]oxazin-3(4H)-one features a brominated benzoxazine core with a methyl group at the 5-position, delivering enhanced reactivity for C–C coupling and functionalization. The electron-deficient oxazinone ring facilitates nucleophilic substitution under mild conditions. This bench-stable scaffold integrates readily into complex heterocyclic systems for medicinal chemistry applications.

Application

6-Bromo-5-methyl-2H-benzo[b][1,4]oxazin-3(4H)-one serves as a versatile heterocyclic building block for medicinal chemistry and materials synthesis. Its bromine substituent enables palladium-catalyzed cross-coupling reactions, while the oxazinone core offers stability and compatibility with diverse functional groups. The methyl group provides a site for further derivatization, enhancing synthetic flexibility in developing API candidates and functionalized scaffolds.
