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

4-Chloro-5-methoxy-2-methylpyrimidine features a trifunctional pyrimidine core enabling direct integration into pharmaceutical intermediates. The chlorine at C4 facilitates nucleophilic substitution, while the methoxy and methyl groups provide steric and electronic modulation. This compound demonstrates robust stability under standard conditions and serves as a key scaffold in kinase inhibitor and antiviral agent synthesis.

Application

4-Chloro-5-methoxy-2-methylpyrimidine serves as a versatile building block in medicinal chemistry, enabling efficient construction of pyrimidine-based scaffolds. Its chloro group facilitates nucleophilic substitution with amines, thiols, and other heteroatoms, while the methoxy and methyl groups provide orthogonal functional handles for further derivatization. The compound exhibits excellent bench stability and compatibility with standard coupling conditions, making it ideal for modular synthesis of kinase inhibitors and antiviral agents.
