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-Bromo-2,2-dimethoxypropane serves as a stable, bench-ready reagent for selective etherification and carbonyl protection. The geminal dimethoxy group enhances solubility and stability, while the bromide enables efficient substitution under mild conditions. This reagent integrates cleanly into synthetic sequences requiring controlled C–O bond formation.

Application

1-Bromo-2,2-dimethoxypropane serves as a reliable electrophilic brominating agent and a versatile building block in organic synthesis. Its dimethoxy group stabilizes the adjacent carbon, enhancing bench stability and enabling selective transformations. It functions effectively in nucleophilic substitution reactions, particularly for introducing bromoalkyl moieties under mild conditions. The molecule demonstrates good functional group tolerance and facilitates clean reactions with amines, thiols, and enolates, making it valuable for constructing complex intermediates in medicinal chemistry and process development workflows.
