    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

Tributyl(methyl)phosphonium dimethyl phosphate serves as a stable, moisture-tolerant phosphonium reagent for efficient Wittig-type olefination. This compound integrates a methyl-substituted phosphonium center with a dimethyl phosphate counterion, enhancing solubility in polar aprotic solvents and enabling smooth reaction initiation under standard conditions.

Application

Tributyl(methyl)phosphonium dimethyl phosphate serves as a stable, bench-ready reagent for the Wittig-type olefination of aldehydes and ketones, enabling efficient synthesis of terminal and internal alkenes. Its phosphonium salt structure offers excellent functional group tolerance and ease of handling, with byproducts readily removed during standard aqueous workups. This reagent facilitates high-yielding transformations in complex molecule assembly, particularly valuable in the construction of conjugated systems and heterocyclic scaffolds.
