    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

Methyl 5-bromo-3-fluorothiophene-2-carboxylate features a thiophene core bearing bromo and fluoro substituents at the 5- and 3-positions, respectively, with a methyl ester at C2. This electron-deficient heterocycle integrates readily into cross-coupling reactions, enabling efficient access to complex functionalized building blocks in medicinal chemistry and materials synthesis.

Application

Methyl 5-bromo-3-fluorothiophene-2-carboxylate serves as a versatile building block in medicinal chemistry and materials science, enabling palladium-catalyzed cross-coupling reactions due to its bromo substituent. The fluorine atom enhances metabolic stability and modulates electronic properties, while the ester group provides a handle for further functionalization. Its bench-stable nature and compatibility with standard synthetic protocols facilitate efficient access to substituted thiophene scaffolds relevant to pharmaceutical and agrochemical development.
