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-methoxy-4-methylpyrimidine is a bench-stable, electron-deficient pyrimidine derivative featuring orthogonal functional groups enabling selective derivatization. The chloro substituent at C2 facilitates nucleophilic substitution, while the methoxy and methyl groups at C5 and C4, respectively, provide steric and electronic modulation. This compound serves as a key intermediate in the synthesis of bioactive heterocycles and agrochemical scaffolds.

Application

2-Chloro-5-methoxy-4-methylpyrimidine serves as a versatile pyrimidine scaffold for medicinal chemistry and agrochemical synthesis, enabling efficient functionalization via nucleophilic substitution at the C2 position. Its methoxy and methyl groups provide orthogonal reactivity and enhanced solubility, while the chlorine facilitates coupling with amines, thiols, and heterocycles under mild conditions. Bench-stable and readily purified by column chromatography, it functions as a key building block in the construction of bioactive heterocyclic frameworks.
