    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

2,5-Dibromobenzaldehyde features two bromine substituents at the 2 and 5 positions of the benzene ring, creating a highly electron-deficient aromatic core. This configuration enhances reactivity in cross-coupling processes and enables direct functionalization at the aldehyde terminus. The compound exhibits excellent stability under standard conditions and serves as a key intermediate in synthesizing complex pharmaceuticals and advanced materials.

Application

2,5-Dibromobenzaldehyde serves as a versatile building block in the synthesis of functionalized aromatic scaffolds. Its dual bromine substituents enable efficient palladium-catalyzed cross-coupling reactions, while the aldehyde group supports selective transformations such as reductive amination, Wittig reactions, and oxime formation. The compound exhibits excellent bench stability and facilitates straightforward purification, making it well-suited for iterative synthetic sequences in medicinal chemistry and materials science.
