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

Description

4-Chloro-3-iodobenzaldehyde features a dual-heteroatom substitution pattern on the aromatic ring, delivering enhanced reactivity in cross-coupling processes. The aldehyde group enables direct functionalization, while the iodine moiety serves as a high-efficiency handle for palladium-catalyzed transformations. This compound exhibits excellent stability under standard bench conditions and integrates readily into complex molecular architectures.

Application

4-Chloro-3-iodobenzaldehyde serves as a versatile building block in transition-metal-catalyzed cross-coupling reactions, enabling the construction of biaryl scaffolds under palladium-mediated conditions. The ortho-iodo and para-chloro substituents provide orthogonal reactivity for sequential functionalization, while the aldehyde group offers direct access to imines, hydrazones, and other downstream transformations. Bench-stable and compatible with standard purification methods, it facilitates efficient synthesis of complex aromatic intermediates for medicinal chemistry and materials applications.
