Description

Flunitrazepam-D7 is a deuterated internal standard of the benzodiazepine derivative flunitrazepam, essential for precise analytical quantification. This high-purity, isotopically labeled compound is critical for ensuring accuracy and reliability in sensitive mass spectrometry-based analyses. It is primarily required by analytical laboratories, forensic toxicologists, and pharmaceutical researchers for method development, validation, and routine testing.

Application

• Internal standard for the quantitative analysis of flunitrazepam in biological matrices (e.g., blood, urine, hair) using LC-MS/MS or GC-MS.
• Method development and validation in forensic and clinical toxicology laboratories.
• Pharmaceutical research and development for pharmacokinetic and metabolic studies.
• Quality control and assurance in reference material and diagnostic kit manufacturing.
• Use in doping control and workplace drug testing programs.
• Calibration standard for ensuring regulatory compliance in analytical procedures.

Quality Control

Our Flunitrazepam-D7 is manufactured under strict quality systems to ensure the highest standards of purity and isotopic enrichment required for analytical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing results for identity, purity (HPLC), chemical purity, isotopic purity (D-enrichment), and residual solvents. We support compliance with ISO 17025 and GLP principles for forensic and clinical research.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as indicated on the label or COA. Keep the container in a dry, well-ventilated place. For long-term storage, consider storing desiccated at -20°C.
