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.

Description

5-Bromo-4-chloro-6-iodothieno[2,3-d]pyrimidine features a trihalogenated heterocyclic core enabling precise diversification in cross-coupling workflows. The strategic placement of bromo, chloro, and iodo substituents supports sequential functionalization, while the electron-deficient thienopyrimidine scaffold enhances reactivity in Pd-catalyzed transformations. This compound serves as a key building block for advanced pharmaceutical intermediates and materials with tailored electronic properties.

Application

5-Bromo-4-chloro-6-iodothieno[2,3-d]pyrimidine serves as a versatile multi-heteroatom building block for the synthesis of advanced heterocyclic scaffolds. Its orthogonal halogenation pattern enables sequential cross-coupling reactions under palladium catalysis, facilitating precise diversification at multiple positions. The compound exhibits excellent bench stability and compatibility with standard Suzuki, Stille, and Negishi coupling conditions, making it ideal for medicinal chemistry campaigns and API intermediate development.
