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-Bromo-1-naphthaldehyde features a bromine substituent at the para position relative to the aldehyde group on a naphthalene core, delivering enhanced reactivity in cross-coupling transformations. This electron-deficient aromatic aldehyde serves as a key building block for pharmaceutical intermediates and functional materials, offering improved solubility and stability under standard reaction conditions.

Application

4-Bromo-1-naphthaldehyde serves as a versatile building block in synthetic organic chemistry, enabling direct functionalization at the aldehyde and bromine sites. Its naphthyl framework provides extended conjugation and enhanced stability for use in Suzuki-Miyaura couplings, Ullmann reactions, and Friedel-Crafts transformations. The molecule exhibits excellent bench stability and facilitates straightforward purification, making it well-suited for iterative synthesis of biaryl scaffolds and heterocyclic intermediates relevant to medicinal chemistry and materials science.
