    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

5-Phenyl-2,4-dihydro-3H-pyrazol-3-one features a conjugated enone system flanked by a phenyl ring and a pyrrolidinone core, enabling participation in cycloaddition reactions. The scaffold exhibits enhanced stability under standard conditions and integrates readily into heterocyclic libraries for medicinal chemistry applications.

Application

5-Phenyl-2,4-dihydro-3H-pyrazol-3-one serves as a versatile heterocyclic building block for medicinal chemistry and synthetic organic applications. Its enolizable carbonyl and C5-phenyl substitution enable reliable participation in nucleophilic additions, cycloadditions, and transition-metal-catalyzed couplings. The scaffold exhibits bench stability, moderate solubility in common organic solvents, and compatibility with standard purification methods, facilitating integration into multi-step syntheses of functionalized pyrazole derivatives and pharmacologically relevant scaffolds.
