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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

3-Bromo-2-chlorobenzaldehyde features a sterically constrained aromatic core with complementary halogen substituents, enabling selective cross-coupling reactions. The aldehyde group provides a reactive handle for nucleophilic additions and condensation chemistry under standard conditions. This molecule integrates seamlessly into complex synthetic sequences requiring precise functional group placement.

Application

3-Bromo-2-chlorobenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The aldehyde functionality facilitates downstream transformations such as reductive amination and Wittig olefination, while the bromo and chloro substituents offer complementary sites for selective functionalization. Bench-stable and readily purified by distillation, it functions effectively in multi-step syntheses requiring precise regiocontrol.
