Overview
Dehydrocorydaline Standard is a purified alkaloid compound primarily used as a reference material in pharmaceutical and biochemical research. It is isolated from plants of the Corydalis genus, which are traditionally used in Chinese medicine. The standard is critical for ensuring accuracy in quantitative analysis and method validation. In modern laboratories, it serves as a benchmark for identifying and quantifying dehydrocorydaline in complex matrices. Its standardized properties make it indispensable for quality control in herbal medicine production and pharmacological studies investigating its potential therapeutic effects.
Physical and Chemical Properties
Dehydrocorydaline Standard typically presents as a fine white crystalline powder with defined chromatographic and spectroscopic characteristics. The compound demonstrates stability under proper storage conditions but may degrade when exposed to prolonged light or humidity. Its molecular structure includes a tetrahydroprotoberberine skeleton, contributing to its UV absorption properties at ~230nm and 280nm. These properties are exploited in HPLC-UV analytical methods. The compound's moderate solubility in organic solvents facilitates sample preparation for various analytical techniques.
Main Applications
The primary application of Dehydrocorydaline Standard is in analytical chemistry for method development and validation. It is routinely used in HPLC and LC-MS systems to establish calibration curves and verify system suitability. In pharmaceutical research, the standard supports investigations into the compound's potential bioactive properties, including its reported anti-inflammatory and cardiovascular effects. Quality control laboratories utilize it to authenticate and standardize herbal extracts containing Corydalis-derived components.
Safety and Storage
While not classified as highly hazardous, Dehydrocorydaline Standard requires careful handling in laboratory settings. Personal protective equipment including gloves and safety glasses should be worn during preparation and handling. For long-term stability, the material should be stored in amber glass vials with PTFE-lined caps at refrigerated temperatures (2-8°C). Desiccants are recommended to prevent moisture absorption. The standard should be allowed to reach room temperature before opening to minimize condensation.
B2B Procurement Guide
When sourcing Dehydrocorydaline Standard, prioritize suppliers who provide comprehensive certificates of analysis (CoA) including purity assessment by multiple analytical methods (HPLC, NMR). Batch-to-batch consistency is crucial for reliable analytical results. Consider purchasing small quantities initially to verify performance in your specific applications. For research institutions requiring frequent use, establishing contracts with reputable manufacturers can ensure consistent supply and potentially reduce costs. Always verify the supplier's quality management certifications and analytical capabilities.
