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.

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

2,3-Dihydrobenzo[b][1,4]dioxine-5-carbaldehyde features a rigid, electron-rich dioxane ring fused to a benzene core, delivering enhanced stability and predictable reactivity. The pendant aldehyde group enables direct incorporation into Suzuki-Miyaura couplings, Buchwald-Hartwig aminations, and other C–C or C–heteroatom bond-forming processes. This scaffold serves as a key building block in the synthesis of bioactive heterocycles and functional materials, particularly where planarity and solubility are critical.

Application

2,3-Dihydrobenzo[b][1,4]dioxine-5-carbaldehyde serves as a versatile building block in medicinal chemistry, enabling efficient access to bioactive heterocycles. Its aldehyde functionality facilitates reductive amination, Grignard additions, and Wittig reactions under mild conditions. The rigid, oxygenated bicyclic core provides excellent metabolic stability and favorable pharmacokinetic properties, making it valuable for scaffold hopping and lead optimization in CNS-targeted drug discovery.
