    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

Isoxazolidine hydrochloride offers a stable, moisture-tolerant scaffold for synthetic applications. This heterocyclic compound integrates readily into complex molecular architectures due to its reactive C–N bond and defined stereochemistry. Its crystalline form enables straightforward handling under standard bench conditions, facilitating use in medicinal chemistry and combinatorial synthesis workflows.

Application

Isoxazolidine hydrochloride serves as a stable, bench-ready synthon for the construction of isoxazole heterocycles and related bioactive scaffolds. Its functional group tolerance enables reliable use in multistep synthesis, while the protonated form enhances solubility and simplifies purification. Functions as a key intermediate in the development of nitrogen-containing heterocycles relevant to medicinal chemistry and agrochemical research.
