    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-Chloroterephthalic acid serves as a key building block in the synthesis of functionalized aromatic polymers and coordination complexes. Featuring two carboxylic acid groups flanked by a chlorine substituent at the para position, it enables selective derivatization under standard conditions. The electron-withdrawing chlorine enhances reactivity in coupling reactions, while maintaining stability during processing. This structure facilitates integration into advanced materials for applications in catalysis and electronic devices.

Application

2-Chloroterephthalic acid serves as a versatile building block in synthetic organic chemistry, enabling direct incorporation of chlorinated aromatic functionality into complex scaffolds. Its dual carboxylic acid groups facilitate amide and ester formation, while the ortho-chloro substituent supports palladium-catalyzed cross-coupling reactions. The compound exhibits good bench stability and is readily purified by recrystallization, making it well-suited for use in medicinal chemistry and materials synthesis workflows.
