    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 pyrazole carboxylic acid features a methoxycarbonyl group at the 5-position and a methyl substituent at the 1-position, delivering enhanced solubility and stability. The conjugated system supports efficient coupling reactions, while the carboxylic acid moiety enables direct derivatization. A robust scaffold for bioactive molecule synthesis under standard conditions.

Application

5-(Methoxycarbonyl)-1-methyl-1H-pyrazole-3-carboxylic acid serves as a versatile building block for heterocyclic synthesis, enabling efficient access to pyrazole-based scaffolds prevalent in medicinal chemistry. Its dual functionality—carboxylic acid and ester groups—facilitates sequential derivatization, while the methyl substitution enhances bench stability and simplifies purification. The molecule functions reliably in standard coupling reactions and participates in cycloaddition processes, offering predictable reactivity for constructing complex molecular architectures under routine laboratory conditions.
