Description

Hexahydro-2H-Azepin-2-One, Sodium Salt is the sodium salt derivative of caprolactam, a key intermediate in polymer chemistry. This compound matters for its enhanced solubility and reactivity profile compared to the parent lactam, making it a versatile building block for specialty synthesis. It is primarily needed by manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for applications requiring a modified, salt-form of the ε-caprolactam structure.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those containing modified lactam rings.
• Polymer Modification: Used as a co-monomer or initiator in the production of specialized polyamides (nylons) to alter thermal properties, solubility, or processing characteristics.
• Agrochemical Synthesis: Acts as a building block for creating advanced herbicides, fungicides, or plant growth regulators with tailored efficacy.
• Chemical Research & Development: Employed in organic synthesis laboratories for developing new compounds, catalysts, or ligands due to its reactive salt form.
• Cross-linking Agent: Potential use in resins and coatings where its structure can contribute to forming stable polymeric networks.
• Caprolactam Derivative Production: A starting material for manufacturing other caprolactam-based salts and derivatives with specific industrial applications.

Quality Control

Our Hexahydro-2H-Azepin-2-One, Sodium Salt is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) documenting results for assay, related substances, residual solvents, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place at a controlled room temperature (15-25°C). The container must be kept tightly sealed in a dry environment to prevent absorption of atmospheric moisture and carbon dioxide, which can compromise product quality.
