Description

Formamidine-13C Acetate is a stable isotope-labeled compound where the carbon atom in the formamidine moiety is the carbon-13 (13C) isotope. This product is essential as a high-purity internal standard and tracer in quantitative mass spectrometry, enabling precise and accurate analytical measurements. It is primarily required by research institutions, pharmaceutical companies, and CROs (Contract Research Organizations) engaged in advanced metabolic studies, pharmacokinetics, and proteomics research.

Application

• Internal standard for the quantitative LC-MS/MS analysis of related guanidine compounds in biological matrices.
• Tracer molecule in metabolic pathway studies and drug metabolism research (DMPK).
• Critical reagent in the synthesis of isotopically labeled pharmaceuticals for clinical trials.
• Use in proteomics research for peptide quantification and protein turnover studies.
• Component in environmental analysis for tracing specific chemical degradation pathways.
• Reference material for calibrating mass spectrometers and validating analytical methods.

Quality Control

Our Formamidine-13C Acetate is manufactured under strict quality systems to ensure exceptional isotopic and chemical purity, critical for sensitive analytical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >99 atom % 13C), chemical purity (by HPLC/NMR), and absence of specific impurities. We support compliance with cGMP and ISO 9001 standards for research and development use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This product is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent degradation. Keep container tightly sealed when not in use.
