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

5-Bromo-4-chloro-1H-pyrrolo[2,3-b]pyridine features a fused bicyclic core with complementary halogen substituents enabling direct functionalization in cross-coupling reactions. The electron-deficient pyrrolopyridine scaffold supports efficient C–H activation and transition metal catalysis. This bench-stable heterocycle serves as a key intermediate for pharmaceutical and agrochemical synthesis.

Application

5-Bromo-4-chloro-1H-pyrrolo[2,3-b]pyridine serves as a versatile heterocyclic building block for the synthesis of biologically active compounds. Its complementary halogenation pattern enables sequential cross-coupling reactions under palladium catalysis, facilitating efficient construction of complex scaffolds. The molecule exhibits excellent bench stability and compatibility with standard reaction conditions, simplifying purification and scale-up. Functions effectively in Suzuki-Miyaura, Stille, and Negishi coupling protocols for medicinal chemistry and materials science applications.
