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-5-methoxybenzaldehyde features a chlorine atom at the ortho position and a methoxy group at the para position relative to the aldehyde, creating a uniquely electron-deficient aromatic scaffold. This configuration enhances reactivity in electrophilic substitution and facilitates coupling reactions under mild conditions. The aldehyde functionality enables direct incorporation into complex molecular architectures via imine formation or reductive amination. Its bench-stable nature supports reliable handling in synthetic workflows.

Application

2-Chloro-5-methoxybenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to substituted heterocycles and biologically active scaffolds. Its electron-withdrawing chlorine and methoxy groups provide orthogonal reactivity for selective functionalization, while the aldehyde functionality facilitates imine formation, reductive amination, and coupling reactions. Bench-stable and amenable to standard purification techniques, it functions reliably in multistep synthetic sequences.
