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+

Description

6-Bromo-2,3-dihydro-4H-chromen-4-one features a brominated chromenone core with enhanced reactivity at the C6 position. This bench-stable scaffold integrates readily into Suzuki-Miyaura couplings and serves as a key intermediate in synthesizing bioactive heterocycles. The electron-deficient carbonyl and sterically accessible site enable efficient functionalization under mild conditions.

Application

6-Bromo-2,3-dihydro-4H-chromen-4-one serves as a versatile scaffold for the synthesis of bioactive heterocycles and pharmaceutical intermediates. Its bromine substituent enables palladium-catalyzed cross-coupling reactions, while the lactone functionality supports nucleophilic addition and ring manipulation. The compound exhibits good bench stability and facilitates efficient functionalization in standard synthetic workflows.
