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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+

Description

6-O-tert-Butyl 3-O-methyl 2-amino-5,7-dihydro-4H-thieno[2,3-c]pyridine-3,6-dicarboxylate features a sterically shielded tert-butyl ether and methyl ester at the 6- and 3-positions, respectively, enhancing stability and solubility. The electron-rich thienopyridine core bears a strategically positioned amino group, enabling direct incorporation into diverse heterocyclic scaffolds via cross-coupling or cyclization reactions under standard conditions.

Application

6-O-tert-Butyl 3-O-methyl 2-amino-5,7-dihydro-4H-thieno[2,3-c]pyridine-3,6-dicarboxylate serves as a versatile building block for the synthesis of thienopyridine-based heterocycles. The protected diester functionality enables selective transformations, while the 2-amino group facilitates downstream coupling and cyclization reactions. Bench-stable and compatible with standard synthetic protocols, it functions as a key intermediate in the construction of bioactive scaffolds relevant to medicinal chemistry and process development.
