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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

Methyl benzoylformate serves as a key synthon in heterocyclic synthesis, featuring a reactive α-keto ester moiety flanked by aromatic and methyl groups. This structure enables efficient cyclization under mild conditions, delivering substituted pyrones and related scaffolds with high regiocontrol. The compound exhibits stability under standard bench protocols and integrates seamlessly into multi-step sequences for natural product analogs.

Application

Methyl benzoylformate serves as a versatile synthon in organic synthesis, enabling efficient construction of substituted benzoic acid derivatives and heterocyclic scaffolds. Its α-keto ester functionality facilitates nucleophilic additions, Claisen condensations, and cyclization reactions under mild conditions. The compound exhibits good bench stability and is readily purified by distillation or chromatography, making it suitable for scalable laboratory applications.
