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

2-Chloro-5-(methylthio)pyrimidine serves as a pivotal heterocyclic scaffold in medicinal chemistry, integrating a reactive chlorine atom with a sulfur-tethered methyl group. This combination enables selective functionalization in cross-coupling reactions and facilitates the construction of complex pyrimidine-based pharmaceuticals under mild conditions. The molecule exhibits robust stability and favorable solubility profiles in common organic solvents.

Application

2-Chloro-5-(methylthio)pyrimidine serves as a versatile building block in medicinal chemistry, enabling efficient construction of pyrimidine-based scaffolds through nucleophilic substitution. The chloro group at C2 facilitates coupling with amines, thiols, and other nucleophiles under mild conditions, while the methylthio substituent provides moderate electron donation and orthogonal reactivity. Its bench stability and compatibility with common reaction protocols make it well-suited for iterative synthesis campaigns in API development.
