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-hydroxybenzaldehyde features a strategically positioned chloro group adjacent to a hydroxyl-bearing aromatic ring, enabling enhanced reactivity in electrophilic substitution and condensation processes. This ortho-hydroxy aldehyde integrates readily into complex heterocyclic scaffolds and serves as a key intermediate in the synthesis of bioactive compounds and functionalized dyes under standard conditions.

Application

3-Chloro-2-hydroxybenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to bioactive heterocycles. Its ortho-hydroxyl and aldehyde functionalities facilitate intramolecular cyclizations and metal-catalyzed coupling reactions. The chloro substituent enhances electrophilic reactivity and provides a handle for further functionalization, while the compound exhibits good bench stability and ease of purification—ideal for multi-step synthetic sequences.
