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

2-Chloro-4-hydroxybenzaldehyde features a hydroxyl group flanked by electron-withdrawing chlorine and aldehyde functionalities, enabling direct coupling in heterocyclic synthesis. This ortho-directing system facilitates regioselective functionalization under mild conditions, while the phenolic moiety enhances solubility in polar solvents and supports metal coordination in catalytic systems.

Application

2-Chloro-4-hydroxybenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to substituted benzimidazoles, quinolines, and other heterocyclic scaffolds. The ortho-chloro and para-hydroxyl groups provide complementary sites for electrophilic substitution and coupling reactions, while the aldehyde functionality facilitates reductive amination, Ullmann-type couplings, and condensation reactions. Bench-stable and readily purified by recrystallization, it offers reliable performance in multi-step syntheses.
