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-Bromo-5-methylbenzaldehyde features a bromine atom at the ortho position relative to the aldehyde group and a methyl substituent at the meta position, creating a sterically accessible, electron-deficient aromatic ring. This configuration enables efficient coupling in cross-coupling reactions and facilitates downstream functionalization in synthetic sequences. The aldehyde functionality provides a reactive handle for nucleophilic additions and condensation chemistry.

Application

2-Bromo-5-methylbenzaldehyde serves as a versatile building block in synthetic organic chemistry, enabling palladium-catalyzed cross-coupling reactions due to its compatible bromo and aldehyde functionalities. The methyl group enhances electronic stability and directs ortho-selective functionalization. Its bench-stable nature and compatibility with common protecting groups facilitate efficient synthesis of complex aromatic scaffolds, including those found in pharmaceutical intermediates and agrochemicals.
