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

4-(tert-Butyl)-2-hydroxybenzaldehyde features a sterically shielded tert-butyl group and a phenolic hydroxyl, enhancing stability and solubility in organic media. This electron-rich aldehyde integrates readily into synthesis pathways requiring robust, bench-stable aromatic building blocks.

Application

4-(tert-Butyl)-2-hydroxybenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to substituted phenolic scaffolds. Its ortho-hydroxyl group facilitates chelation-assisted transformations, while the sterically hindered tert-butyl substituent enhances stability and modulates electronic properties. The aldehyde functionality permits straightforward derivatization via condensation, reductive amination, or Grignard addition, offering robust utility in multi-step syntheses.
