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-dichloro-7-methylthieno[3,2-d]pyrimidine features a fused heterocyclic core with electron-deficient character, enabling robust coupling reactions in medicinal chemistry. The methyl group enhances lipophilicity and metabolic stability, while the dichloro substitution pattern facilitates selective functionalization at C2 and C4 positions under standard conditions. This scaffold serves as a key building block for kinase inhibitors and other bioactive molecules.

Application

2,4-dichloro-7-methylthieno[3,2-d]pyrimidine serves as a versatile building block in medicinal chemistry, enabling efficient construction of purine and thienopyrimidine-based scaffolds. Its dual chlorines facilitate nucleophilic substitution under mild conditions, while the methyl group enhances metabolic stability. The compound exhibits excellent bench stability and compatibility with standard coupling protocols, making it ideal for modular synthesis of kinase inhibitors and other bioactive heterocycles.
