    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

4-Methyloxazole is a heterocyclic compound featuring a five-membered ring with oxygen and nitrogen atoms, bearing a methyl group at the 4-position. This substitution enhances electron density at the ring’s C5 position, promoting reactivity in electrophilic aromatic substitution and facilitating use in synthetic routes to bioactive molecules. The compound exhibits good thermal stability and handles well under standard bench conditions.

Application

4-Methyloxazole serves as a versatile heterocyclic building block in synthetic organic chemistry, offering enhanced stability and predictable reactivity in electrophilic substitution and transition-metal-catalyzed coupling reactions. Its methyl group provides a site for selective functionalization, while the oxazole core exhibits favorable compatibility with common protecting groups and reaction conditions, enabling efficient access to complex scaffolds in medicinal chemistry and materials science applications.
