    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 moiety integrates readily into Suzuki-Miyaura cross-coupling reactions under standard conditions, delivering functionalized heteroaryl products with high efficiency. The dimethylthiophene scaffold imparts enhanced stability and solubility, enabling reliable performance in complex synthetic sequences.

Application

(2,5-Dimethylthiophen-3-yl)boronic acid serves as a versatile building block in Suzuki-Miyaura cross-coupling reactions, enabling efficient construction of biaryl and heteroaryl scaffolds. Its thiophene core offers enhanced stability and favorable solubility, while the boronic acid group facilitates reliable coupling under mild conditions. The 2,5-dimethyl substitution pattern provides steric and electronic modulation, improving functional group tolerance and simplifying purification. This reagent is well-suited for medicinal chemistry campaigns requiring access to substituted thiophene derivatives.
