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

2-Bromo-3-chloronitrobenzene features a nitro group flanked by bromo and chloro substituents on adjacent ring positions, creating a highly electron-deficient aromatic scaffold. This configuration enables selective coupling reactions in cross-coupling protocols and facilitates downstream functionalization in pharmaceutical and agrochemical synthesis. The molecule exhibits robust stability under standard reaction conditions.

Application

2-Bromo-3-chloronitrobenzene serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The bromo group facilitates efficient Suzuki, Stille, or Negishi coupling, while the chloro and nitro functionalities offer additional handles for selective transformations. Its bench-stable nature and compatibility with standard reaction conditions make it ideal for multi-step syntheses requiring precise functional group manipulation.
