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

4H,6H,7H-Pyrano[4,3-d][1,3]thiazole-2-carbaldehyde features a fused heterocyclic core with a reactive aldehyde group at the 2-position, enabling direct incorporation into synthetic sequences. The extended π-system enhances electronic delocalization, while the pyran-thiazole scaffold provides structural rigidity and improved solubility in polar solvents. This compound serves as a key intermediate for bioactive molecule synthesis.

Application

4H,6H,7H-Pyrano[4,3-d][1,3]thiazole-2-carbaldehyde serves as a versatile heterocyclic building block for medicinal chemistry and materials synthesis. Its fused tricyclic scaffold enables selective functionalization at the aldehyde position, facilitating coupling reactions, imine formation, and downstream derivatization. The molecule exhibits bench stability and good solubility, supporting efficient purification and integration into multi-step synthetic sequences.
