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

4-Bromo-5-methylthiophene-2-carbaldehyde features a brominated thiophene core with a methyl substituent and an aldehyde group at the 2-position. This electron-deficient heterocycle serves as a key building block in the synthesis of functionalized aromatic systems, particularly for coupling reactions requiring precise regiocontrol and stability under standard conditions.

Application

4-Bromo-5-methylthiophene-2-carbaldehyde serves as a versatile building block in heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions and functionalization at the aldehyde and bromide sites. Its bench-stable nature and compatibility with standard protecting group strategies facilitate efficient access to complex thienyl scaffolds relevant to medicinal chemistry and materials science.
