For professionals in the pharmaceutical industry, understanding the precise specifications of chemical intermediates is non-negotiable. Vilazodone Carboxylic Acid (CAS 163521-19-5), a vital precursor in the synthesis of the antidepressant Vilazodone, requires meticulous attention to its chemical and physical properties. This article outlines the key specifications that buyers should look for when sourcing this critical intermediate.

Key Chemical and Physical Properties
Vilazodone Carboxylic Acid is characterized by its molecular formula C26H26N4O3 and a molecular weight of 442.52. These fundamental properties are consistent across reputable suppliers. The appearance is typically described as a light yellow to off-white powder, which is a standard indicator for its physical state and initial purity assessment.

Purity Standards for Pharmaceutical Use
The purity of Vilazodone Carboxylic Acid is a critical determinant of its suitability for pharmaceutical synthesis. Most suppliers guarantee a purity level of 98% or higher. This high purity is essential to minimize the formation of unwanted byproducts during the synthesis of Vilazodone and to meet the rigorous standards set by regulatory bodies for Active Pharmaceutical Ingredients (APIs). Manufacturers should be able to provide detailed analytical reports, such as HPLC chromatograms, confirming this purity.

Storage and Handling Recommendations
While specific handling instructions should always be followed from the Safety Data Sheet (SDS) provided by the manufacturer, common recommendations for Vilazodone Carboxylic Acid include storage in a cool, dry place, often under inert atmosphere and refrigerated (2-8°C) to maintain stability, as it can be hygroscopic. Proper handling procedures are crucial to preserve its quality and prevent degradation.
