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.

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

3-Bromo-2-chloro-5-nitropyridine features a tri-substituted pyridine core with complementary halogen and nitro functionalities, enabling selective cross-coupling and functionalization in late-stage diversification. The electron-deficient ring facilitates nucleophilic substitution under mild conditions, while the orthogonal reactivity of bromo and chloro groups allows sequential transformations. This scaffold delivers high stability and predictable regiochemistry in synthetic workflows.

Application

3-Bromo-2-chloro-5-nitropyridine serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling selective cross-coupling reactions via its halogen substituents. The nitro group provides a handle for reduction to an amine, while the ortho-halogen arrangement facilitates controlled functionalization. Its bench-stable nature and compatibility with Pd-catalyzed coupling protocols make it well-suited for modular heterocycle construction and late-stage diversification in API development.
