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

This oxazine aldehyde features a fused heterocyclic core with a reactive aldehyde group at the 6-position, enabling direct coupling in synthetic transformations. The electron-deficient carbonyl and conjugated system enhance reactivity in nucleophilic additions, while the dihydrooxazine scaffold provides structural rigidity. Designed for efficient integration into complex molecular architectures, this compound serves as a key intermediate in medicinal chemistry and materials synthesis.

Application

3-Oxo-3,4-dihydro-2H-benzo[b][1,4]oxazine-6-carbaldehyde serves as a versatile heterocyclic building block for medicinal chemistry and process development. Its ortho-aldehyde and ketone functionalities enable sequential functionalization in multistep syntheses, including reductive amination and condensation reactions. The scaffold exhibits bench stability and compatibility with common protecting group strategies, facilitating efficient access to complex oxazine-based pharmacophores.
