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+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

rel-(3aR,4S,7R,7aS)-Hexahydro-4,7-methanoisobenzofuran-1,3-dione is a rigid, bridged bicyclic diester featuring defined stereochemistry at all chiral centers. This configuration imparts high conformational stability and predictable reactivity in asymmetric synthesis. The molecule serves as a key chiral synthon for Diels-Alder reactions and enantioselective transformations, where its locked geometry enables precise stereochemical control.

Application

rel-(3aR,4S,7R,7aS)-Hexahydro-4,7-methanoisobenzofuran-1,3-dione serves as a valuable chiral synthon in asymmetric synthesis, enabling stereoselective construction of complex bicyclic architectures. Its rigid, functionalized framework exhibits excellent bench stability and compatibility with standard transformations, facilitating efficient access to bioactive heterocycles and natural product analogs through controlled Diels-Alder cycloadditions and subsequent functionalization.
