Cis Tosylate Product Overview
Cis Tosylate is a high-quality intermediate supplied by Vubrix Pharma Private Limited, a leading API manufacturer and exporter based in Surat, Gujarat, India. Cis Tosylate is a stereochemically defined intermediate essential for the synthesis of Ketoconazole and related antifungal APIs. The cis configuration is critical for the biological activity of the final API, making stereochemical purity a key quality attribute. Vubrix Pharma employs advanced synthetic chemistry and analytical techniques to ensure high stereochemical purity and consistent quality. Our manufacturing process is designed to minimize epimerization and maintain the desired cis configuration throughout the synthesis pathway.

Manufacturing Process
Vubrix Pharma manufactures Cis Tosylate using a controlled, documented synthesis route developed and optimized by our process chemistry team. Raw materials are sourced from qualified vendors and verified against specification before use. Each batch follows a master batch record with defined critical process parameters, in-process controls, and hold points to ensure consistent quality.
The Cis Tosylate manufacturing process includes reaction setup, controlled conditions for yield and selectivity, work-up and isolation, purification (crystallization, filtration, or chromatographic steps as required), and drying under validated parameters. In-process samples are tested at defined stages to confirm reaction progress, impurity profile, and intermediate quality before proceeding.
Finished Cis Tosylate batches undergo comprehensive release testing including identity confirmation, assay, related substances/impurities profiling, residual solvents (ICH Q3C), water content, heavy metals screening, and appearance. Only material meeting predefined specifications and quality standards is approved for release and dispatch.
Our Surat facility supports scale-up from pilot batches to commercial production, enabling seamless transition from development quantities to ongoing supply agreements. Process validation documentation, stability data, and change control records are maintained to support regulatory submissions and customer audits.
