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

tert-Butyl 5-aminothiophene-2-carboxylate features a thiophene core functionalized with both amino and ester groups, enabling direct incorporation into diverse heterocyclic scaffolds. The tert-butyl ester enhances solubility and stability during synthetic manipulations, while the pendant amine offers a reactive handle for further derivatization. This compound serves as a key intermediate in the development of bioactive thiophene-based molecules.

Application

tert-Butyl 5-aminothiophene-2-carboxylate serves as a versatile building block in heterocyclic synthesis, enabling efficient access to functionalized thiophene scaffolds. The pendant amino group facilitates direct electrophilic substitution or coupling reactions, while the tert-butyl ester offers robust protection under acidic conditions and simplifies purification. Its bench-stable nature and compatibility with standard coupling protocols make it ideal for medicinal chemistry and process development workflows.
