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+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

Pyrido[3,4-d]thiazole is a heterocyclic scaffold featuring fused pyridine and thiazole rings, offering enhanced stability and tunable electronic properties. This rigid, planar architecture supports π-stacking interactions and facilitates integration into functional materials. The nitrogen and sulfur atoms provide coordination sites for metal complexes, enabling applications in catalysis and molecular sensing.

Application

Pyrido[3,4-d]thiazole serves as a versatile heterocyclic scaffold in medicinal chemistry, enabling the construction of bioactive molecules through established coupling and functionalization protocols. Its fused ring system exhibits favorable stability and orthogonal reactivity, facilitating selective derivatization at multiple positions. This framework functions effectively in standard synthetic workflows, supporting applications in kinase inhibitor development and targeted drug discovery.
