    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

2,3-Quinolinedicarboxylic acid features a rigid, electron-deficient quinoline core paired with two carboxylic acid groups at the 2- and 3-positions. This structural motif enables strong coordination to metal ions in supramolecular assemblies and facilitates incorporation into metal-organic frameworks. The molecule exhibits enhanced solubility in polar solvents compared to unsubstituted quinolines, simplifying handling in aqueous or mixed solvent systems.

Application

2,3-Quinolinedicarboxylic acid serves as a versatile building block in heterocyclic synthesis, enabling efficient access to quinoline-based scaffolds through established coupling and cyclization protocols. Its dual carboxylic acid functionality supports diverse derivatization—particularly in metal coordination, peptide coupling, and polymer synthesis—while maintaining bench stability and ease of purification. The molecule functions effectively in the construction of bioactive compounds and functional materials, offering predictable reactivity in standard organic transformations.
