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-Fluoro-3,4-dihydro-2H-benzo[b][1,4]oxazine is a fluorinated heterocyclic scaffold featuring a fused benzene and oxazine ring system. This electron-deficient core enables selective incorporation into bioactive molecules, particularly in medicinal chemistry applications where enhanced metabolic stability and membrane permeability are required. The para-fluorine substitution modulates electronic properties without significant steric perturbation, supporting efficient derivatization under standard coupling conditions.

Application

7-Fluoro-3,4-dihydro-2H-benzo[b][1,4]oxazine serves as a versatile heterocyclic building block in medicinal chemistry, enabling the construction of bioactive scaffolds through standard functionalization at the dihydrooxazine ring. Its fluorinated aromatic system enhances metabolic stability and modulates electronic properties, while the saturated oxazine core offers site-specific reactivity for C–H functionalization, coupling reactions, and derivatization. Bench-stable and compatible with common purification methods, it facilitates efficient synthesis of pharmaceutical intermediates and API candidates.
