Blue Eye Bio
specializes in providing high-precision Deuterated Reference Standards. Our Sildenafil-D3 and Sildenafil-D8 are specifically synthesized for advanced Bio-analytical testing. These stable isotope-labeled compounds are essential for laboratories requiring the highest level of isotopic and chemical purity for quantitative analysis
Sildenafil-D3 & Sildenafil-D8
Product Item | CAS Number | Isotopic Purity | Application |
Sildenafil-D3 | 1126745-90-1 | ≥ 99% Atom D | LC-MS Internal Std |
Sildenafil-D8 | 951385-65-2 | ≥ 99% Atom D | PK / Bio-analysis |
Chemical Structure Characteristics (Isotopic Labeling):These are deuterated compounds. By replacing specific hydrogen atoms in the molecular structure with stable deuterium atoms, they produce a significant mass shift in mass spectrometry.
Key Technical Specifications:
Chemical Purity: ≥ 98% - 99% (HPLC).
Isotopic Purity: ≥ 99% Atom D
Solubility: Soluble in DMSO, methanol, or acetonitrile; compatible with standard laboratory mobile phases
Pharmacokinetic (PK) Studies: Used as a stable internal standard to track drug metabolism in complex biological matrices. It is used to study the absorption, distribution, metabolism, and excretion of drugs in organisms. Because D3/D8 is almost identical to regular sildenafil in chemical properties but has a different molecular weight, researchers can trace the metabolic pathways of drug molecules.
When developing sildenafil formulations, pharmaceutical companies must demonstrate that they have the same bioavailability as the original drug. This requires the use of high-quality isotope-labeled internal standards for comparison.
Unrivaled Isotopic Integrity: Our synthesis process ensures minimal un-labeled (D0) Sildenafil contamination, preventing analytical interference.
Agile Sourcing: Leveraging our Strategic Supply Chain Alliance to provide rare analytical standards with rapid global fulfillment.
Bespoke Packaging: We offer specialized low-volume vials (1mg, 5mg, 10mg) optimized for laboratory precision.
For laboratory use and R&D purposes only. Not for human or diagnostic use.
