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

Methyl 4-chloro-4-oxobutanoate features a reactive β-keto ester scaffold flanked by a chloro substituent, enabling direct functionalization at the carbonyl center. This electrophilic motif integrates readily into synthetic sequences requiring selective alkylation or condensation. The molecule exhibits enhanced stability under standard bench conditions and displays favorable solubility in common organic solvents, streamlining handling in process development workflows.

Application

Methyl 4-chloro-4-oxobutanoate serves as a versatile building block in synthetic organic chemistry, enabling efficient access to γ-chloro-α-keto ester derivatives. Its electrophilic carbonyl and pendant chloride facilitate nucleophilic substitution and enolization reactions, supporting applications in heterocycle synthesis and functional group interconversions. The compound exhibits good bench stability and is amenable to purification via distillation or column chromatography, making it well-suited for use in multi-step synthetic sequences requiring high reproducibility and scalability.
