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 2-amino-5-chlorothiophene-3-carboxylate features a thiophene core bearing amino and chloro substituents at adjacent positions, enabling strategic functionalization in heterocyclic synthesis. The methyl ester group provides a handle for selective derivatization under standard conditions. This bench-stable compound integrates readily into advanced intermediates for pharmaceutical and agrochemical development.

Application

Methyl 2-amino-5-chlorothiophene-3-carboxylate serves as a versatile building block for heterocyclic synthesis, enabling efficient access to substituted thiophene scaffolds. The amino and chloro groups provide orthogonal functional handles for Suzuki-Miyaura, Buchwald-Hartwig, and nucleophilic substitution reactions. Its bench-stable nature and compatibility with standard purification methods make it well-suited for medicinal chemistry and process development workflows.
