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

3-Chloro-2-methylbenzaldehyde features a chlorinated aromatic ring with adjacent methyl and aldehyde groups, delivering enhanced reactivity in electrophilic substitution. This ortho-substituted scaffold enables efficient integration into pharmaceutical intermediates and functional materials. The molecule exhibits favorable stability under standard bench conditions, facilitating straightforward handling in synthetic workflows.

Application

3-Chloro-2-methylbenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to substituted benzimidazoles, benzoxazoles, and other heterocyclic scaffolds via standard condensation and cyclization protocols. Its ortho-chloro and methyl substituents provide controlled reactivity and steric modulation, enhancing regioselectivity in electrophilic aromatic substitution and coupling reactions. Bench-stable and readily purified by distillation or recrystallization, it functions effectively in multi-step syntheses requiring functional group tolerance and predictable transformation pathways.
