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-Hydroxy-2-nitrobenzaldehyde features a hydroxyl group flanked by a nitro substituent and aldehyde functionality, enabling its use in conjugated systems. This electron-deficient aromatic scaffold integrates readily into synthetic intermediates for dyes, pharmaceuticals, and ligands. The ortho-nitro group enhances reactivity toward nucleophiles while the phenolic OH supports metal coordination.

Application

5-Hydroxy-2-nitrobenzaldehyde serves as a versatile building block in synthetic organic chemistry, enabling direct access to substituted benzimidazoles and other heterocyclic scaffolds via condensation reactions. The ortho-nitro and hydroxyl groups provide strong directing effects for electrophilic substitution, while the aldehyde functionality facilitates facile coupling with amines and hydrazines. Bench-stable and compatible with standard purification methods, it functions effectively in multi-step syntheses requiring functional group tolerance and predictable reactivity.
