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-Methyl-1-propyl-1H-pyrazole-4-carbaldehyde features a pyrazole core functionalized with a methyl group at C5 and a propyl chain at N1, delivering enhanced lipophilicity and metabolic stability. The aldehyde at C4 enables direct coupling in multistep syntheses, serving as a key scaffold for bioactive heterocycles. This bench-stable reagent integrates readily into medicinal chemistry campaigns requiring tailored heteroaromatic platforms.

Application

5-Methyl-1-propyl-1H-pyrazole-4-carbaldehyde serves as a versatile building block in heterocyclic synthesis, enabling efficient access to pyrazole-based scaffolds through standard carbonyl transformations. Its aldehyde functionality facilitates reductive amination, Wittig reactions, and condensation with hydrazines or amines under mild conditions. The methyl and propyl substituents provide steric and electronic modulation, enhancing stability and solubility for bench-scale applications. This compound functions effectively in medicinal chemistry campaigns requiring functionalized pyrazoles with improved metabolic profiles.
