    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

2,5-Difluoroterephthalic acid features a rigid aromatic core with two fluorine substituents positioned at the 2 and 5 ring positions, imparting enhanced electron-withdrawing character and improved solubility in polar solvents. This structural motif enables efficient integration into metal-organic frameworks and functional polymers, where its defined geometry supports precise network assembly under standard conditions.

Application

2,5-Difluoroterephthalic acid serves as a valuable building block for the synthesis of fluorinated aromatic polymers and bioactive heterocycles. Its two carboxylic acid groups enable straightforward amide, ester, and imide formation, while the ortho-fluoro substituents offer enhanced electrophilicity for subsequent nucleophilic aromatic substitution. The compound exhibits good bench stability and facilitates purification via recrystallization, making it well-suited for scalable synthetic applications in medicinal chemistry and materials science.
