Description

Sulfanilamide-13C6 is a stable isotope-labeled analog of the classic sulfonamide antibiotic, where six carbon atoms are replaced with the carbon-13 isotope. This compound is essential as an internal standard for the precise quantification of sulfanilamide in complex biological and environmental matrices using mass spectrometry. It is a critical tool for researchers and quality control laboratories in the pharmaceutical, clinical research, and analytical chemistry sectors. The product is supplied with high chemical and isotopic purity to ensure reliable and reproducible analytical results.

Application

• Internal Standard for LC-MS/MS and GC-MS: Primary application for accurate quantification of sulfanilamide in pharmacokinetic, metabolomic, and bioanalytical studies.
• Pharmaceutical Research & Development: Used in drug metabolism and disposition (DMPK) studies to trace the fate of sulfonamide drugs.
• Veterinary Drug Residue Analysis: Critical for ensuring food safety by detecting sulfonamide antibiotic residues in meat, milk, and other animal products.
• Environmental Monitoring: Employed in the analysis of water and soil samples for sulfonamide contaminant tracking.
• Clinical Diagnostics: Supports the development and validation of diagnostic assays for therapeutic drug monitoring.
• Isotope Dilution Mass Spectrometry (IDMS): Serves as the spike material for this gold-standard quantitative analytical technique.
• Metabolic Pathway Tracing: Facilitates research into bacterial and mammalian metabolic pathways involving sulfonamides.

Quality Control

Every batch of Sulfanilamide-13C6 is manufactured and analyzed under strict quality systems. We guarantee high chemical purity and isotopic enrichment, typically ≥98% chemical purity and ≥99 atom % 13C, confirmed by advanced analytical techniques including NMR and Mass Spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, isotopic abundance, and solvent content is provided with each shipment to ensure traceability and compliance with your research protocols.

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); ensure the container is sealed after each use to prevent absorption of atmospheric moisture. For long-term storage, consider storing under an inert atmosphere.
