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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

Methyl 5-amino-4-cyano-3-methylthiophene-2-carboxylate features a thiophene core functionalized with amino, cyano, methylthio, and ester groups, enabling integration into diverse heterocyclic architectures. This electron-deficient scaffold facilitates coupling reactions under mild conditions and serves as a key intermediate in the synthesis of bioactive thienyl derivatives.

Application

Methyl 5-amino-4-cyano-3-methylthiophene-2-carboxylate serves as a versatile building block in heterocyclic synthesis, enabling efficient access to substituted thiophene scaffolds relevant to medicinal chemistry and agrochemical development. The molecule combines an amino group for derivatization, a cyano function for nucleophilic transformations, and a methylthio substituent compatible with oxidative or displacement reactions. Its bench-stable nature and straightforward purification support scalable synthesis workflows.
