    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

Ethyl 2-(oxetan-3-ylidene)acetate features a strained oxetane ring fused to an α,β-unsaturated ester system, enabling efficient cycloaddition reactions. This reactive scaffold integrates readily into complex molecular architectures via inverse electron-demand Diels–Alder processes, offering high chemoselectivity and mild reaction conditions. The molecule exhibits bench-stable handling with tolerance to moisture and air, simplifying use in synthetic workflows.

Application

Ethyl 2-(oxetan-3-ylidene)acetate serves as a versatile Michael acceptor and heterocyclic building block in synthetic organic chemistry. Its strained oxetane ring imparts enhanced reactivity, enabling efficient conjugate additions with nucleophiles under mild conditions. The molecule functions as a key intermediate in the construction of complex oxygen-containing heterocycles and bioactive scaffolds, offering excellent bench stability and compatibility with diverse functional groups.
