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

7-(Diethylamino)-2-oxo-2H-chromene-3-carbaldehyde features a conjugated chromenone core with a diethylamino group enhancing electron density at the C7 position and a formyl group at C3 enabling nucleophilic addition. This scaffold integrates readily into synthetic routes for fluorescent probes and photoactive materials, offering tunable photophysical properties under standard conditions.

Application

7-(Diethylamino)-2-oxo-2H-chromene-3-carbaldehyde serves as a versatile building block in the synthesis of fused heterocycles and bioactive scaffolds. Its conjugated aldehyde and enone functionality enables efficient Michael additions, aldol condensations, and Pechmann-type cyclizations. The diethylamino group enhances electron density at the chromenone core, facilitating nucleophilic transformations while maintaining bench stability and ease of purification under standard organic protocols.
