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 boronate ester integrates a sterically shielded tetramethylcyclopentadienyl core with a 4-methylnaphthalen-1-yl group, enabling stable coupling in Suzuki-Miyaura reactions. The electron-rich naphthyl moiety enhances reactivity while the bulky methyl substituents confer moisture tolerance and bench stability under standard conditions.

Application

4,4,5,5-Tetramethyl-2-(4-methylnaphthalen-1-yl)-1,3,2-dioxaborolane serves as a stable, bench-ready boronate building block for Suzuki-Miyaura cross-coupling reactions. Its naphthyl moiety enables efficient construction of biaryl scaffolds with enhanced solubility and thermal stability. The tetramethyl-substituted dioxaborolane ring ensures high functional group tolerance and minimal protodeboronation, facilitating reliable coupling under standard conditions. This reagent functions effectively in late-stage diversification and heterocyclic synthesis workflows.
