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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

2-Chloro-7-fluoroquinazoline delivers a highly reactive platform for constructing advanced heterocyclic architectures. The ortho-chloro and para-fluoro substituents enable selective coupling under mild conditions, while the electron-deficient core supports efficient integration into pharmaceutical scaffolds and functional materials.

Application

2-Chloro-7-fluoroquinazoline serves as a versatile building block in medicinal chemistry, enabling direct functionalization at C2 and C7 positions via palladium-catalyzed cross-coupling reactions. Its dual electrophilic sites offer high reactivity in Suzuki, Stille, and Buchwald-Hartwig transformations, facilitating rapid access to substituted quinazoline scaffolds. Bench-stable and readily purified by flash chromatography, it functions efficiently in multi-step synthesis of kinase inhibitors and other bioactive heterocycles.
