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 heterocyclic scaffold features a fused pyridine-oxazine core with inherent stability and tunable reactivity. The saturated dihydropyridine ring enables selective functionalization, while the oxygen atom enhances polarity and solubility. This structure serves as a key building block in medicinal chemistry for accessing bioactive molecules through modular derivatization pathways.

Application

3,4-Dihydro-2H-pyrido[3,2-b][1,4]oxazine serves as a versatile heterocyclic scaffold in medicinal chemistry, enabling efficient construction of bioactive molecules through standard functionalization at the pyridine and oxazine rings. Its stability under routine reaction conditions and compatibility with common coupling and reduction protocols facilitate downstream derivatization. Functions as a key building block for CNS-targeted compounds and kinase inhibitors, offering predictable reactivity in transition-metal-catalyzed transformations.
