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

2,4-Dichloro-5-ethylpyrimidine serves as a pivotal electrophilic scaffold in heterocyclic synthesis, featuring reactive chlorine sites at C2 and C4 that enable selective functionalization. The ethyl substituent at C5 enhances solubility and modulates electronic properties, while the pyrimidine core provides a robust platform for coupling reactions under mild conditions. This compound demonstrates excellent stability and compatibility with diverse reaction environments.

Application

2,4-Dichloro-5-ethylpyrimidine serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient construction of pyrimidine-based scaffolds. The dichloro substitution pattern facilitates nucleophilic aromatic substitution reactions at C2 or C4, while the ethyl group at C5 provides steric and electronic modulation. Its bench-stable nature and compatibility with diverse coupling partners make it well-suited for iterative functionalization in API development workflows.
