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
Excepted Quantity	$0.00

Description

Methyl 2-formyl-4-hydroxybenzoate features a strategically positioned aldehyde and phenolic hydroxyl group, enabling direct functionalization in synthetic sequences. This ortho-aldehyde-substituted ester integrates readily into complex molecular architectures under mild conditions. The formyl moiety offers high reactivity for nucleophilic additions, while the hydroxyl group enhances solubility and facilitates downstream derivatization. Bench-stable and moisture-tolerant, it serves as a robust building block for pharmaceutical intermediates and functionalized aromatic systems.

Application

Methyl 2-formyl-4-hydroxybenzoate serves as a versatile synthetic building block for the construction of bioactive heterocycles and pharmaceutical intermediates. Its ortho-formyl and phenolic hydroxyl groups enable efficient cyclization reactions, while the methyl ester provides a handle for selective transformations. The compound exhibits good bench stability and facilitates straightforward purification, making it well-suited for iterative synthesis in medicinal chemistry workflows.
