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-5-methoxy-4-methylbenzoic acid features a strategically positioned bromine atom and electron-donating methoxy and methyl groups that enhance reactivity in cross-coupling transformations. This aromatic carboxylic acid serves as a key building block for pharmaceutical intermediates and functional materials, offering improved solubility and stability under standard conditions.

Application

2-Bromo-5-methoxy-4-methylbenzoic acid serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient late-stage functionalization via palladium-catalyzed cross-coupling reactions. The carboxylic acid group facilitates direct derivatization, while the bromine atom provides a reliable handle for Suzuki, Stille, or Negishi couplings. Its methyl and methoxy substituents offer predictable electronic effects and enhanced solubility, supporting scalable synthesis and straightforward purification.
