    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

3,5-Di-tert-butylphenol features two bulky tert-butyl groups flanking a phenolic hydroxyl, creating a sterically shielded aromatic system. This configuration imparts exceptional thermal and oxidative stability, making it ideal for use in high-performance antioxidants and polymer stabilizers. The electron-donating nature of the substituents enhances reactivity in radical scavenging processes.

Application

3,5-Di-tert-butylphenol serves as a sterically hindered phenolic building block enabling robust protection strategies and facilitating selective functionalization in complex synthesis. Its ortho-tert-butyl groups confer exceptional bench stability and resistance to oxidation, while the phenolic OH group participates reliably in esterification, etherification, and metal-catalyzed coupling reactions. Functions as a key intermediate in the construction of hindered antioxidants and chiral ligands.
