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-methylbenzaldehyde features a chlorine atom at the para position and a methyl group at the ortho position relative to the aldehyde, creating a sterically hindered, electron-deficient aromatic ring. This configuration enhances reactivity in nucleophilic addition and coupling reactions, particularly in pharmaceutical synthesis and agrochemical intermediates. The compound exhibits bench-stable handling characteristics under standard conditions.

Application

4-Chloro-2-methylbenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient construction of substituted aromatic scaffolds. Its ortho-methyl and para-chloro substituents provide distinct electronic and steric modulation, enhancing reactivity in nucleophilic additions, condensation reactions, and transition-metal-catalyzed couplings. The aldehyde functionality offers high synthetic versatility for downstream transformations including imine formation, reductive amination, and Ullmann-type coupling processes. Bench-stable and readily purified by distillation or recrystallization, it supports scalable applications in both research and process development workflows.
