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

2,4-Dichlorobenzo[4,5]thieno[3,2-d]pyrimidine features a fused polycyclic core combining thiophene and pyrimidine motifs, delivering enhanced electron-deficient character and structural rigidity. This scaffold serves as a high-performance building block in medicinal chemistry, particularly for kinase inhibitors and bioactive heterocycles. The dichloro substitution pattern enhances metabolic stability and modulates electronic properties for targeted interactions.

Application

2,4-Dichlorobenzo[4,5]thieno[3,2-d]pyrimidine serves as a versatile heterocyclic building block for medicinal chemistry and materials science, enabling efficient construction of fused polycyclic scaffolds. Its dual chloro substituents facilitate palladium-catalyzed cross-coupling reactions, while the rigid, planar core supports π-stacking interactions in target-directed synthesis. The compound exhibits excellent bench stability and compatibility with standard purification methods, making it well-suited for iterative synthetic campaigns in API development and functional materials design.
