    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

(S)-Oxiran-2-ylmethyl butyrate is a chiral epoxide intermediate featuring a stereodefined oxirane ring and a pendant butyrate ester. This configurationally stable scaffold enables selective ring-opening reactions in asymmetric synthesis, particularly for constructing complex oxygenated heterocycles. The molecule's bench-stable nature and compatibility with nucleophilic reagents streamline downstream functionalization in medicinal chemistry workflows.

Application

(S)-Oxiran-2-ylmethyl butyrate serves as a versatile chiral building block in asymmetric synthesis, enabling stereoselective ring-opening reactions under mild conditions. The epoxide functionality exhibits high regioselectivity with nucleophiles, while the pendant ester group provides a handle for further functionalization. Bench-stable and compatible with common reaction protocols, it facilitates efficient access to complex oxygenated intermediates relevant to natural product and pharmaceutical synthesis.
