Your trusted source for Reference Standards, manufactured and certified in-house

Visit us at booth 1F31 to explore our growing portfolio of pharmaceutical reference standards, including impurities, nitrosamines, and stable isotope-labeled compounds. We’ll also share our expanding service capabilities—from custom synthesis to the isolation, identification, and characterization of unknown impurities—to support your pharmaceutical research and analytical development.

Our team looks forward to discussing your analytical challenges, reconnecting with customers and partners, and exploring new opportunities to work together.

While our previously developed Tacrolimus-13C-d2 standard was successfully used in a range of analytical applications, several clients working with this large and structurally complex molecule indicated that a greater mass difference was preferred for highly sensitive LC-MS/MS methods. In response, our laboratory rapidly adapted to this market need and developed Tacrolimus-13C-d4—demonstrating our flexibility and commitment to delivering reference standards aligned with evolving customer requirements.

Tacrolimus-13C-d4 has been produced with high isotopic enrichment and excellent chemical purity as detailed in its COA, making it well suited for analytical applications including:

• LC-MS/MS quantitative analysis
• Bioanalytical method development and validation
• Pharmacokinetic and therapeutic drug monitoring studies
• GLP-compliant analytical workflows

The development of a highly enriched multi-labeled tacrolimus standard presents significant synthetic and analytical challenges, and materials of this type can be difficult to source at consistently high quality.
