    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

5-Formyl-1H-pyrrole-2-carboxylic acid features a dual functional group motif: an electron-rich pyrrole core paired with reactive aldehyde and carboxylic acid termini. This combination enables direct coupling in multistep syntheses, facilitating the construction of complex heterocyclic architectures under mild conditions. The molecule’s stability and compatibility with diverse reaction environments support its use in medicinal chemistry and materials development workflows.

Application

5-Formyl-1H-pyrrole-2-carboxylic acid serves as a versatile bifunctional building block for heterocyclic synthesis, enabling direct coupling via formyl and carboxylic acid functionalities. Its bench-stable nature and compatibility with standard amide coupling, reductive amination, and cycloaddition protocols facilitate efficient access to complex pyrrole-based scaffolds. Functions effectively in medicinal chemistry lead optimization and materials science applications requiring tailored nitrogen-containing frameworks.
