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

7-Bromo-5-chloro-4-azaindole integrates a bromo substituent at the 7-position and a chloro group at the 5-position onto a 4-azaindole core, delivering enhanced electronic modulation and structural rigidity. This combination enables efficient coupling in cross-coupling protocols and facilitates targeted functionalization in medicinal chemistry campaigns.

Application

7-Bromo-5-chloro-4-azaindole serves as a versatile building block for the synthesis of bioactive heterocycles, leveraging its dual halogen substituents for palladium-catalyzed cross-coupling reactions. The electron-deficient 4-azaindole core enhances regioselectivity in electrophilic substitutions and facilitates integration into pharmaceutical scaffolds. Bench-stable and readily purified by chromatography, it functions effectively in iterative synthetic sequences requiring orthogonal functional group tolerance.
