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+

Description

Isochroman-1,3-dione features a fused bicyclic core with two carbonyl groups in a 1,3-relationship, conferring enhanced stability and distinct electronic properties. This scaffold serves as a key building block in synthetic routes to bioactive molecules, particularly those requiring electron-deficient aromatic systems. Its rigid geometry facilitates precise spatial control in molecular design.

Application

Isochroman-1,3-dione serves as a versatile building block in synthetic organic chemistry, enabling efficient construction of complex heterocyclic scaffolds. Its fused benzene-furanone architecture provides inherent stability and predictable reactivity, facilitating nucleophilic additions and cycloaddition processes. The molecule functions effectively in transition-metal-catalyzed transformations and offers excellent functional group tolerance, making it well-suited for iterative synthesis workflows in medicinal chemistry and materials science.
