Description

1-(4-Methoxy-Benzenesulfonyl)-Piperazinehydrochloride is a high-purity sulfonamide derivative and piperazine-based building block, essential for advanced organic synthesis. Its core value lies in providing a reliable and structurally defined intermediate for the development of novel active pharmaceutical ingredients (APIs) and fine chemicals. This compound is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries engaged in drug discovery and process development.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of potential drug candidates, particularly those targeting central nervous system (CNS) disorders, infectious diseases, and metabolic conditions.
• Agrochemical Research: Used in the development of novel herbicides, fungicides, and insecticides, leveraging the sulfonamide moiety for biological activity.
• Chemical Biology & Proteomics: Serves as a versatile scaffold or linker for designing chemical probes to study enzyme function and protein-protein interactions.
• Material Science: Potential precursor for the synthesis of specialty polymers and functional materials with specific sulfonamide properties.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for use in client-specific, multi-step synthetic routes.

Quality Control

Our 1-(4-Methoxy-Benzenesulfonyl)-Piperazinehydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting standards for research and development use. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics is provided with every shipment.

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 (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. Keep away from incompatible materials.
