    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

4-Bromothiophene-3-carbaldehyde features a brominated thiophene ring fused to an aldehyde group, enabling direct functionalization in cross-coupling and cyclization reactions. The electron-deficient heterocycle facilitates nucleophilic attack, while the aldehyde serves as a versatile handle for imine formation and derivatization under mild conditions.

Application

4-Bromothiophene-3-carbaldehyde serves as a versatile building block in synthetic organic chemistry, enabling direct incorporation of both bromine and aldehyde functionalities into complex molecular architectures. Its compatibility with palladium-catalyzed cross-coupling reactions and ease of functionalization via aldehyde transformations make it a practical reagent for constructing heterocyclic scaffolds and pharmaceutical intermediates. Bench-stable and readily purified, it supports scalable synthesis workflows.
