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.

Description

2,2-Difluorobenzo[d][1,3]dioxole-5-carbaldehyde features a rigid, electron-deficient aromatic core paired with a highly reactive aldehyde group. This configuration enables direct integration into complex heterocycles and facilitates efficient coupling in transition-metal-catalyzed transformations. The difluorinated ring enhances metabolic stability and modulates electronic properties for applications in medicinal chemistry and advanced materials synthesis.

Application

2,2-Difluorobenzo[d][1,3]dioxole-5-carbaldehyde serves as a versatile building block in medicinal chemistry, enabling direct incorporation of a difluorinated aromatic core with orthogonal reactivity. The aldehyde group facilitates efficient coupling reactions, while the 1,3-dioxole ring enhances metabolic stability and modulates electronic properties. Its bench-stable nature and compatibility with standard functional group transformations make it ideal for rapid scaffold diversification in API development.
