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

Description

2-Chloro-6,7-dihydro-4H-pyrano[4,3-d]thiazole is a heterocyclic scaffold featuring a fused pyran-thiazole core with a chlorine substituent. This electron-deficient system enables direct incorporation into complex molecular architectures, offering enhanced metabolic stability and favorable solubility profiles for medicinal chemistry applications.

Application

2-Chloro-6,7-dihydro-4H-pyrano[4,3-d]thiazole serves as a versatile heterocyclic building block for medicinal chemistry and process development. Its fused pyrano-thiazole core exhibits robust bench stability and facilitates efficient functionalization at the C2 position. The chlorine substituent enables palladium-catalyzed cross-coupling reactions, while the saturated dihydro ring provides favorable solubility and orthogonal reactivity in multi-step syntheses. This scaffold functions effectively in constructing complex molecular architectures under standard reaction conditions.
