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-Amino-3-hydroxybenzaldehyde features a fused ortho-dihydroxyamine and aldehyde motif, enabling direct coordination to metal ions in catalytic systems. This arrangement supports redox-active ligand design and facilitates integration into functionalized scaffolds for materials chemistry and bioconjugation workflows.

Application

2-Amino-3-hydroxybenzaldehyde serves as a versatile building block in medicinal chemistry, enabling direct access to substituted quinoline and benzoxazole scaffolds via cyclization reactions. Its ortho-difunctionalized aromatic core facilitates efficient metal-catalyzed coupling processes and offers predictable reactivity in condensation-based heterocycle formation. Bench-stable and readily purified by recrystallization, it supports scalable synthesis workflows with high functional group tolerance.
