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-Chloro-3,4-dimethoxybenzaldehyde features a chlorine atom and two methoxy groups positioned ortho to the aldehyde functionality, creating a highly electron-rich aromatic core. This configuration enhances reactivity in coupling reactions while maintaining stability under standard conditions. The molecule serves as a key building block for pharmaceutical intermediates and functionalized dyes.

Application

2-Chloro-3,4-dimethoxybenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, offering predictable reactivity at the aldehyde function. Its electron-rich aromatic core enhances performance in nucleophilic additions and transition-metal-catalyzed couplings. The ortho-chloro substituent provides a handle for further functionalization via cross-coupling or substitution reactions. Bench-stable and readily purified by recrystallization, it functions effectively in standard synthetic workflows requiring high functional group tolerance.
