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

4,5-Dimethyl-1,3-dioxol-2-one is a bench-stable, moisture-tolerant cyclic carbonate featuring two methyl groups that enhance solubility in polar organic solvents. This electron-deficient heterocycle serves as a selective acylating agent in peptide synthesis and coupling reactions, where its strained ring facilitates nucleophilic attack under mild conditions.

Application

4,5-Dimethyl-1,3-dioxol-2-one serves as a stable, bench-ready synthon for the construction of substituted β-lactones and heterocyclic scaffolds. Its electrophilic carbonyl functionality enables selective reactions with nucleophiles such as amines and alcohols, facilitating the synthesis of functionalized intermediates under mild conditions. The molecule exhibits excellent stability and ease of purification, making it a practical choice for iterative synthetic sequences in medicinal chemistry and process development.
