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+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

tert-Butyl 2-formyl-4,5-dihydrothieno[2,3-c]pyridine-6(7H)-carboxylate features a fused thienopyridine core with a strategically positioned formyl group and a bench-stable tert-butyl ester. This electrophilic scaffold integrates readily into heterocyclic synthesis, enabling direct access to functionalized analogs via nucleophilic addition or condensation reactions.

Application

tert-Butyl 2-formyl-4,5-dihydrothieno[2,3-c]pyridine-6(7H)-carboxylate serves as a versatile heterocyclic building block for medicinal chemistry and synthetic methodology development. The formyl group enables direct functionalization via nucleophilic addition or condensation reactions, while the dihydrothienopyridine core provides a rigid, electron-deficient scaffold suitable for transition metal-catalyzed coupling processes. Bench-stable and amenable to standard purification methods, it facilitates efficient access to complex fused heterocycles relevant to pharmaceutical research.
