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

5-Chloro-2-hydroxy-3-methylbenzaldehyde features a unique trifunctional scaffold combining a chloro group, phenolic hydroxyl, and aldehyde moiety on a substituted benzene ring. This electron-deficient aryl system enables selective coupling reactions under mild conditions. The ortho-hydroxyaldehyde motif facilitates chelation in transition metal complexes, while the methyl substituent enhances steric profile and solubility. Bench-stable and moisture-tolerant, this compound serves as a key building block for bioactive heterocycles and functional materials.

Application

5-Chloro-2-hydroxy-3-methylbenzaldehyde serves as a versatile building block in synthetic organic chemistry, enabling efficient access to substituted heterocycles and bioactive scaffolds. Its ortho-hydroxy and aldehyde functionalities facilitate cyclization reactions, while the chloro and methyl groups provide regiochemical control and enhanced metabolic stability. The compound exhibits bench stability and compatibility with common functional group transformations, supporting its use in medicinal chemistry and process development workflows.
