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-1-chloro-3-methoxybenzene features a uniquely substituted aromatic core with orthogonal halogen and methoxy functionalities, enabling selective cross-coupling reactions. The para-directed methoxy group enhances electron density at the ipso position, while the ortho-bromo and meta-chloro substituents provide regiochemical control in Pd-catalyzed transformations. This combination delivers high chemoselectivity in complex molecule assembly.

Application

2-Bromo-1-chloro-3-methoxybenzene serves as a versatile ortho-halogenated building block for palladium-catalyzed cross-coupling reactions, enabling efficient access to substituted biaryls and heterocycles. The methoxy group provides moderate electron-donating character and enhances solubility, while the complementary bromo/chloro functionality allows for selective activation in sequential coupling protocols. Bench-stable and readily purified by column chromatography, it functions reliably in standard synthetic workflows requiring halogen-directed functionalization.
