Description

1-Benzyl-5-Ethyl-5-Isopentylbarbituric Acid CAS NO 73680-98-5 is a synthetic barbiturate derivative, a class of compounds historically significant in medicinal chemistry. This compound serves as a key intermediate or reference standard in pharmaceutical research and development, particularly for studying central nervous system (CNS) activity. It is primarily needed by pharmaceutical R&D laboratories, analytical testing facilities, and fine chemical manufacturers engaged in the synthesis of specialized active pharmaceutical ingredients (APIs) or the production of certified reference materials.

Application

• Pharmaceutical Intermediate: Used in the research and synthesis of novel barbiturate-based compounds for potential therapeutic applications.
• Reference Standard: Serves as a high-purity analytical standard for method development, validation, and quality control in pharmaceutical testing.
• Biochemical Research: Employed in pharmacological studies to investigate the structure-activity relationships (SAR) of barbiturates and their interaction with biological targets.
• Chemical Synthesis: Acts as a specialized building block for organic chemists developing complex molecular architectures in academic and industrial settings.
• Controlled Substance Analysis: Utilized by forensic and regulatory laboratories as a calibration standard for the identification and quantification of related substances.
