Description

Piperazinone, 3-Ethyl-1-(Phenylmethyl)-, (3S)- (9Ci) is a chiral, nitrogen-containing heterocyclic compound that serves as a valuable synthetic intermediate and building block in advanced organic synthesis. Its specific stereochemistry and functional groups make it a critical precursor for the development of novel active pharmaceutical ingredients (APIs) and fine chemicals. This high-purity intermediate is primarily sought by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for constructing complex molecular architectures.

Application

• As a key chiral building block in the asymmetric synthesis of pharmaceutical candidates, particularly for central nervous system (CNS) and cardiovascular targets.
• Utilized in the research and development of protease inhibitors and other enzyme-targeted therapeutics.
• Serves as a precursor for the synthesis of complex ligands and catalysts used in homogeneous catalysis.
• Intermediate in the production of agrochemicals, such as herbicides and fungicides with specific stereochemical requirements.
• Used in academic and industrial R&D for exploring new heterocyclic chemistry and structure-activity relationships (SAR).
• Potential application in the synthesis of advanced materials, including polymers and liquid crystals with tailored properties.

Quality Control

Our production of Piperazinone, 3-Ethyl-1-(Phenylmethyl)-, (3S)- (9Ci) adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure high chemical and enantiomeric purity suitable for demanding synthetic applications. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or storing under an inert atmosphere.
