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

1,2,3,4-Tetramethylbenzene is a highly symmetric, electron-rich aromatic hydrocarbon featuring four methyl groups in close proximity on the benzene ring. This substitution pattern imparts enhanced steric shielding and improved thermal stability compared to less substituted analogs. The molecule exhibits excellent solubility in common organic solvents and serves as a valuable reference standard in mass spectrometry and NMR spectroscopy due to its well-defined, predictable spectral signature.

Application

1,2,3,4-Tetramethylbenzene serves as a valuable synthetic building block in organic chemistry, offering enhanced steric bulk and electronic stabilization due to its four methyl substituents. Its high thermal stability and low reactivity toward electrophilic aromatic substitution enable selective functionalization at less hindered positions. The compound facilitates the construction of complex polycyclic architectures and functions as a scaffold in materials science and medicinal chemistry applications requiring defined molecular rigidity and lipophilicity.
