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

1,2-Oxazole-4-carbaldehyde features a reactive aldehyde group fused to an electron-deficient oxazole ring, enabling direct coupling in heterocyclic synthesis. This bench-stable scaffold integrates readily into bioactive molecule design, offering high functional group tolerance and efficient access to complex nitrogen-containing architectures under standard conditions.

Application

1,2-Oxazole-4-carbaldehyde serves as a versatile synthon in heterocyclic synthesis, enabling direct functionalization at the C4 position via electrophilic or nucleophilic transformations. Its aldehyde group facilitates imine formation and reductive amination, while the oxazole ring provides stability and orthogonal reactivity. The compound exhibits good bench stability and is compatible with common protecting group strategies, making it a practical building block for medicinal chemistry and API development.
