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

This tetramethyl-substituted benzenedipropionic acid features a rigid, electron-rich aromatic core flanked by carboxylic acid groups, enabling precise spatial control in molecular scaffolding. The steric bulk of the methyl substituents imparts enhanced solubility and resistance to decarboxylation under standard conditions.

Application

α,α,α',α'-Tetramethyl-1,3-benzenedipropionic acid serves as a sterically hindered aromatic diacid building block, enabling the synthesis of constrained cycloalkane and heterocyclic scaffolds. Its ortho-dicarboxylic acid functionality facilitates efficient esterification, amide coupling, and cyclization reactions under standard conditions. The tetramethyl substitution enhances bench stability and improves solubility in organic media, simplifying purification and handling in multi-step syntheses.
