    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

Guanidinium dihydrogen phosphate delivers a robust, moisture-tolerant ionic pairing with high thermal stability. This compound integrates a guanidinium cation with a hydrogen phosphate anion, enabling strong hydrogen bonding and charge delocalization. It serves as a reliable reagent in crystal engineering and solid-state studies due to its well-defined lattice architecture and resistance to hydrolysis under ambient conditions.

Application

Guanidinium dihydrogen phosphate serves as a robust, bench-stable catalyst in organic synthesis, enabling efficient proton transfer and stabilizing reactive intermediates. Its dual functionality facilitates acid-base cooperative effects in condensation and cyclization reactions, particularly useful in the construction of nitrogen-containing heterocycles. The salt’s crystalline nature ensures ease of handling and purification, while its compatibility with diverse functional groups supports broad synthetic utility in medicinal chemistry and process development workflows.
