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-Chloro-2,5-dimethoxybenzaldehyde features a chlorine-substituted aromatic ring flanked by two methoxy groups and a formyl moiety, enabling direct incorporation into diverse heterocyclic scaffolds. This electron-deficient aldehyde facilitates efficient coupling reactions under standard conditions, offering high functional group tolerance and stability during synthetic manipulations.

Application

4-Chloro-2,5-dimethoxybenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to substituted aromatic scaffolds. Its aldehyde functionality facilitates reductive amination, Grignard additions, and Ullmann-type coupling reactions. The ortho-dimethoxy substitution pattern enhances regioselectivity in electrophilic functionalization, while the 4-chloro group provides a handle for palladium-catalyzed cross-coupling transformations. Bench-stable and readily purified by crystallization, it supports scalable synthesis workflows.
