Description

Tris Carbonate is a high-purity, inorganic salt widely used as a key buffering agent and chemical intermediate. Its primary value lies in providing a stable, non-volatile source of alkalinity and carbonate ions for sensitive formulations. This product is essential for manufacturers in the pharmaceutical, biotechnology, and specialty chemical industries who require precise pH control and reliable raw material quality. Tris Carbonate CAS NO 68123-29-5 is supplied to meet the stringent demands of research, development, and industrial-scale production.

Application

• Pharmaceutical Buffer Systems: Used in the formulation of parenteral solutions, ophthalmic preparations, and diagnostic reagents where precise pH stability is critical.
• Biochemical Research & Cell Culture: Serves as a component in buffer solutions for electrophoresis, chromatography, and cell culture media preparation.
• Chemical Synthesis: Acts as a carbonate ion source and a mild base in organic synthesis and as a precursor for other tris-based compounds.
• Personal Care & Cosmetics: Employed as a pH adjuster and stabilizer in high-end skincare and haircare formulations.
• Analytical Chemistry: Utilized in the preparation of standard solutions and mobile phases for analytical techniques like HPLC.
• Industrial Processes: Functions as a processing aid and neutralizing agent in various specialty chemical manufacturing operations.

Quality Control

Our Tris Carbonate is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, identification, and impurity profiling. Certificates of Analysis (COA) detailing the results for all specified parameters are provided and can be tailored to meet specific customer or regulatory requirements, including those for pharmaceutical (USP/EP) or research-grade applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial opening to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product quality.
