    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

This 3-(benzyloxy)-4-oxo-4H-pyran-2-carboxylic acid features a benzyl ether-linked pyranone scaffold with a carboxylic acid at C2, enabling direct incorporation into synthetic routes for bioactive heterocycles. The electron-deficient pyrone ring facilitates nucleophilic addition and Diels-Alder reactions under mild conditions.

Application

3-(Benzyloxy)-4-oxo-4H-pyran-2-carboxylic acid serves as a versatile scaffold for the synthesis of bioactive heterocycles and natural product analogs. Its carboxylic acid and enone functionalities enable diverse transformations, including nucleophilic additions, Michael reactions, and decarboxylative couplings. The benzyloxy group provides stable protection under standard conditions and can be selectively removed during late-stage functionalization. This compound functions effectively in multi-step syntheses requiring orthogonality and bench stability.
