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

7-Chloro-5-methylthiazolo[5,4-d]pyrimidine features a fused thiazolopyrimidine core with strategic chlorine and methyl substituents enabling enhanced electron-withdrawing character and metabolic stability. This scaffold integrates readily into kinase inhibitor designs and serves as a key heterocyclic building block in medicinal chemistry campaigns targeting purine-binding sites.

Application

7-Chloro-5-methylthiazolo[5,4-d]pyrimidine serves as a versatile heterocyclic building block for medicinal chemistry and agrochemical research. Its fused thiazolo[5,4-d]pyrimidine core provides enhanced metabolic stability and facilitates diverse functionalization at the 7-chloro and 5-methyl positions. The molecule exhibits bench stability, good solubility in common organic solvents, and compatibility with standard cross-coupling and nucleophilic substitution protocols, enabling efficient access to complex scaffolds in drug discovery workflows.
