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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

8-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2H-benzo[b][1,4]oxazin-3(4H)-one features a boronate ester handle appended to a fused oxazine scaffold, enabling direct coupling in Suzuki-Miyaura transformations. This bench-stable reagent integrates readily into complex molecule assembly, delivering efficient access to functionalized heterocyclic architectures under mild conditions.

Application

8-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2H-benzo[b][1,4]oxazin-3(4H)-one serves as a versatile boronate building block for palladium-catalyzed cross-coupling reactions. Its oxazinone core provides structural rigidity and metabolic stability, while the pinacol boronate group enables efficient C–C bond formation under mild conditions. The compound exhibits excellent bench stability, facile purification, and broad functional group tolerance, making it well-suited for iterative synthesis of complex heterocyclic scaffolds in medicinal chemistry and materials science applications.
