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

This dihydropyranone derivative features a sterically hindered diketone core with two methyl groups at the 4-position, enhancing stability and modulating reactivity. The fused ring system provides a rigid scaffold ideal for asymmetric synthesis and natural product derivatization under standard conditions.

Application

4,4-Dimethyldihydro-2H-pyran-2,6(3H)-dione serves as a versatile β-keto ester surrogate in synthetic organic chemistry, enabling efficient construction of cyclohexanone and substituted pyran scaffolds. Its enhanced stability and defined stereochemical control facilitate reliable Michael additions, aldol condensations, and heterocycle formation under standard reaction conditions. The molecule functions as a key building block for complex carbocyclic and heterocyclic frameworks relevant to medicinal chemistry and natural product synthesis.
