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

3-Bromo-5-fluoro-1H-pyrrolo[2,3-b]pyridine is a heteroaromatic building block featuring strategically positioned bromo and fluoro substituents that enable selective cross-coupling reactions. The electron-deficient pyrrolopyridine core facilitates palladium-catalyzed transformations, while the bench-stable, moisture-tolerant structure supports reliable handling in synthetic workflows.

Application

3-Bromo-5-fluoro-1H-pyrrolo[2,3-b]pyridine serves as a versatile building block for the synthesis of bioactive heterocycles, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The bromo group facilitates Suzuki, Stille, and Negishi couplings, while the fluoro substituent enhances metabolic stability and modulates electronic properties in pharmaceutical scaffolds. Bench-stable and readily purified by flash chromatography, it functions efficiently in multi-step syntheses of kinase inhibitors and CNS-targeted compounds.
