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

6-Chloro-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine is a heterocyclic scaffold featuring a chlorinated pyridine fused to a dihydrooxazine ring. This electron-deficient core integrates readily into synthetic sequences requiring nitrogen-rich, planar architectures. The chlorine substituent enhances reactivity in cross-coupling transformations and provides a handle for downstream functionalization. Bench-stable under standard conditions, it serves as a key intermediate in medicinal chemistry campaigns targeting kinase inhibitors and CNS-active compounds.

Application

6-Chloro-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine serves as a versatile heterocyclic building block in medicinal chemistry, enabling efficient access to substituted pyridine and oxazine scaffolds. Its chloro substituent facilitates nucleophilic substitution reactions, while the dihydrooxazine core offers functional group tolerance and stability under standard synthetic conditions. This compound functions effectively in transition-metal-catalyzed coupling processes and supports the construction of complex molecular architectures relevant to pharmaceutical development.
