    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

Naphthalene-2,7-dicarboxylic acid features two carboxylic acid groups positioned at opposite corners of the naphthalene core, enabling robust coordination in metal-organic frameworks. This rigid, planar scaffold facilitates π-conjugation and enhances structural stability in crystalline assemblies. The molecule integrates readily into porous materials for gas storage and catalytic applications.

Application

Naphthalene-2,7-dicarboxylic acid serves as a versatile building block for conjugated heterocycles and metal–organic frameworks, enabling efficient functionalization via standard esterification, amidation, and coupling reactions. Its rigid aromatic core provides structural stability and predictable electronic properties, while the ortho-disubstituted carboxylic acid groups offer high regioselectivity in multi-step syntheses. The compound exhibits excellent bench stability and facilitates straightforward purification by recrystallization, making it well-suited for industrial R&D workflows and scale-up applications.
