Description

Cilostazol-D11 is a deuterium-labeled analog of the antiplatelet and vasodilator drug Cilostazol, specifically designed for use as an internal standard in quantitative analytical methods. This high-purity stable isotope-labeled compound is essential for ensuring the accuracy and reliability of pharmacokinetic, metabolic, and bioanalytical studies. It is primarily utilized by pharmaceutical R&D laboratories, contract research organizations (CROs), and analytical testing facilities engaged in drug development and quality control.

Application

• Internal Standard for LC-MS/MS and GC-MS analysis in bioanalytical method development and validation.
• Quantitative reference material for pharmacokinetic (PK) and pharmacodynamic (PD) studies of Cilostazol.
• Critical component in drug metabolism and disposition (DMPK) research to track and quantify the parent drug.
• Use in clinical trial sample analysis to ensure data integrity and regulatory compliance.
• Calibration standard in high-performance liquid chromatography (HPLC) and mass spectrometry assays.
• Research tool for studying the biochemical pathways and mechanisms of action of Cilostazol.

Quality Control

Our Cilostazol-D11 is manufactured under strict quality systems to ensure the highest standards of isotopic purity and chemical integrity. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing results for identity, chemical purity, isotopic enrichment, and residual solvents. We adhere to relevant guidelines for analytical reference standards to support your regulatory submissions.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
