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

1,3-Dimethyl-1H-pyrazol-4-ol features a pyrazole core with methyl groups at the 1- and 3-positions, enhancing stability and solubility. The phenolic hydroxyl at the 4-position enables hydrogen bonding and serves as a reactive handle for derivatization. This scaffold exhibits favorable electronic properties and bench-stable behavior under standard conditions, making it a valuable building block in medicinal chemistry and heterocyclic synthesis.

Application

1,3-Dimethyl-1H-pyrazol-4-ol serves as a versatile building block in medicinal chemistry, enabling the synthesis of pyrazole-based heterocycles through standard functionalization protocols. Its stability under routine reaction conditions and compatibility with diverse coupling reactions facilitate efficient access to substituted pyrazole scaffolds. The molecule functions as a key intermediate in the construction of bioactive compounds, particularly those requiring ortho-hydroxylated pyrazole motifs.
