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

6-Bromo-5-fluoropyridin-3-amine features a halogenated pyridine core with complementary bromo and fluoro substituents at adjacent positions, enabling selective functionalization in cross-coupling reactions. The amino group at C3 provides a reactive handle for derivatization, while the electron-withdrawing halogens enhance electrophilicity. This combination supports efficient diversification in medicinal chemistry and materials synthesis under standard conditions.

Application

6-Bromo-5-fluoropyridin-3-amine serves as a versatile building block for the synthesis of bioactive heterocycles, enabling palladium-catalyzed cross-coupling reactions due to its reactive halogen and amine functionalities. The ortho-bromofluoro substitution pattern provides excellent regiocontrol in Suzuki, Buchwald–Hartwig, and other transition-metal-mediated transformations. Its bench-stable crystalline form facilitates handling and purification, making it well-suited for iterative medicinal chemistry campaigns and API intermediate development.
