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-4-chloro-5-methoxybenzoic acid features a densely functionalized aromatic core with complementary halogen and electron-donating methoxy groups. This configuration enables selective coupling reactions in late-stage diversification, particularly in pharmaceutical synthesis where orthogonal reactivity is required. The carboxylic acid moiety offers direct handle for amide or ester formation under standard conditions.

Application

3-Bromo-4-chloro-5-methoxybenzoic acid serves as a versatile building block for the synthesis of substituted aromatic scaffolds in medicinal chemistry and agrochemical research. Its defined substitution pattern enables predictable electrophilic and transition-metal-catalyzed coupling reactions, while the carboxylic acid functionality facilitates direct derivatization or salt formation. Bench-stable and readily purified by recrystallization, it functions reliably in standard cross-coupling, amidation, and esterification workflows.
