    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

This pyrylium salt features a highly electrophilic ring stabilized by three methyl groups, enhancing solubility and reactivity. The tetrafluoroborate counterion ensures excellent stability and compatibility with polar solvents. Designed for efficient arylation and cyclization reactions in synthetic organic chemistry workflows.

Application

2,4,6-Trimethylpyrylium tetrafluoroborate serves as a highly reactive electrophilic synthon in organic synthesis, enabling efficient alkylation of nucleophiles under mild conditions. Its stability and solubility facilitate straightforward handling and purification, while the trimethyl substitution enhances regioselectivity in heterocyclic functionalization. Widely used in the construction of substituted pyrylium salts and related scaffolds, it functions reliably in standard bench-scale transformations.
