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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

2-Bromo-5-hydroxy-4-methoxybenzoic acid features a unique combination of bromine, hydroxyl, and methoxy substituents on a benzoic acid scaffold, enabling selective functionalization in synthetic routes. The electron-withdrawing bromine and polar hydroxyl group enhance reactivity in coupling reactions, while the methoxy moiety improves solubility and stability under standard conditions. This derivative serves as a key intermediate in the development of bioactive aromatic compounds and specialty polymers.

Application

2-Bromo-5-hydroxy-4-methoxybenzoic acid serves as a versatile building block for the synthesis of bioactive heterocycles and pharmaceutical intermediates. Its ortho-bromine enables palladium-catalyzed cross-coupling reactions, while the hydroxyl and methoxy groups offer sites for derivatization or protection. The carboxylic acid functionality facilitates amide bond formation and salt crystallization, enhancing purification and handling. This compound exhibits good bench stability and compatibility with standard synthetic workflows.
