    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-Methyl-2-pyridin-2-ylpyridinium iodide serves as a potent electrophilic reagent in transition-metal-catalyzed cross-coupling reactions. The pyridinium moiety, flanked by electron-deficient and sterically accessible sites, enables efficient C–C bond formation under mild conditions. This bench-stable salt combines high reactivity with ease of handling, streamlining synthetic access to functionalized heteroaryl architectures.

Application

1-Methyl-2-pyridin-2-ylpyridinium iodide serves as a versatile pyridinium salt enabling efficient C–H functionalization and electrophilic substitution reactions. Its stability under ambient conditions and compatibility with diverse reaction media facilitate straightforward incorporation into synthetic sequences. Functions as a key building block for bioactive heterocyclic scaffolds and transition-metal-free catalytic systems, offering predictable reactivity and ease of purification in medicinal chemistry workflows.
