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

Ethyl 5-amino-1-methyl-1H-pyrazole-4-carboxylate features a pyrazole core with complementary amine and ester functionalities, enabling direct incorporation into diverse heterocyclic scaffolds. The electron-rich pyrazole ring enhances reactivity in transition-metal-catalyzed couplings, while the methyl and ethyl substituents provide steric control and solubility advantages under standard conditions.

Application

Ethyl 5-amino-1-methyl-1H-pyrazole-4-carboxylate serves as a versatile building block in heterocyclic synthesis, enabling access to diverse pyrazole-based scaffolds. The amino and ester functionalities offer orthogonal reactivity for derivatization via amidation, acylation, or coupling reactions. Its bench-stable nature and compatibility with standard synthetic protocols facilitate efficient incorporation into medicinal chemistry campaigns and API intermediate development.
