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

3-(Trifluoromethyl)pyridin-4(1H)-one features a trifluoromethyl group at the 3-position of a pyridin-4-one scaffold, imparting enhanced electron-withdrawing character and metabolic stability. This moiety serves as a key building block in medicinal chemistry, integrating readily into bioactive scaffolds via coupling reactions. The compound exhibits good solubility in common organic solvents and maintains stability under standard bench conditions.

Application

3-(Trifluoromethyl)pyridin-4(1H)-one serves as a versatile building block in medicinal chemistry, enabling the synthesis of bioactive heterocycles due to its orthogonal reactivity and metabolic stability. The trifluoromethyl group enhances lipophilicity and membrane permeability, while the pyridinone scaffold participates reliably in Suzuki-Miyaura, Buchwald-Hartwig, and nucleophilic substitution reactions. Bench-stable and readily purified by flash chromatography or recrystallization, it functions efficiently in late-stage functionalization and API precursor development.
