    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

2,7-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrene features two robust boronate ester groups flanking a planar pyrene core, enabling efficient Suzuki-Miyaura coupling under standard conditions. This bifunctional scaffold facilitates the construction of conjugated oligomers and polymers with precise structural control, offering enhanced stability and solubility in organic media.

Application

2,7-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrene serves as a versatile Suzuki coupling building block for the construction of conjugated biaryls and extended π-systems. The sterically protected boronate ester groups enable high stability, mild reaction conditions, and excellent functional group tolerance, facilitating efficient C–C bond formation in multistep syntheses. Its symmetry and robustness make it ideal for constructing advanced materials and heterocyclic scaffolds in organic electronics and medicinal chemistry applications.
