    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

(S)-tert-Butyl 3-(2-hydroxyethyl)piperazine-1-carboxylate features a chiral piperazine core with a pendant hydroxyethyl side chain, enabling selective conjugation in peptide and kinase inhibitor synthesis. The tert-butyl ester group provides stability and convenient deprotection under mild acidic conditions, while the hydroxyl moiety offers ready derivatization for bioconjugation or solubility enhancement in polar media.

Application

(S)-tert-Butyl 3-(2-hydroxyethyl)piperazine-1-carboxylate serves as a versatile chiral building block in medicinal chemistry, enabling efficient access to piperazine-based scaffolds. The pendant hydroxyl group facilitates downstream functionalization via esterification, etherification, or oxidation, while the tert-butyl carbamate provides stability and convenient deprotection under mild acidic conditions. Its stereochemical integrity supports asymmetric synthesis, and the molecule exhibits excellent bench stability and ease of purification—ideal for iterative library construction and API intermediate development.
