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

2-Methyl-4H-chromen-4-one features a fused benzopyrone core with a methyl substituent at the C2 position, conferring enhanced electron density and stability. This scaffold serves as a key intermediate in synthesizing bioactive natural product analogs and functionalized heterocycles under standard conditions.

Application

2-Methyl-4H-chromen-4-one serves as a versatile scaffold in synthetic organic chemistry, enabling efficient access to substituted coumarin derivatives. Its readily available methyl group facilitates electrophilic substitution and functionalization, while the chromenone core exhibits stability under standard reaction conditions. The compound functions as a key building block in the synthesis of natural product analogs and bioactive heterocycles, offering predictable reactivity in Pd-catalyzed cross-coupling and Michael addition processes.
