Description

Salicylic Acid-13C6 is a stable isotope-labeled analog of salicylic acid, where all six carbon atoms are the carbon-13 isotope. This compound is essential as an internal standard for precise quantitative analysis in mass spectrometry-based applications, ensuring accuracy and reliability in complex matrices. It is primarily utilized by analytical laboratories, pharmaceutical researchers, and CROs engaged in pharmacokinetic studies, metabolic profiling, and quality control of salicylic acid-containing products.

Application

• Internal standard for the quantification of salicylic acid and its metabolites in biological samples (e.g., plasma, urine) via LC-MS/MS or GC-MS.
• Use in stable isotope dilution assays for high-precision analytical method development and validation.
• Critical reagent in pharmaceutical research for studying the absorption, distribution, metabolism, and excretion (ADME) of salicylic acid.
• Calibration standard in clinical and forensic toxicology to ensure accurate measurement of salicylate levels.
• Tool for metabolic pathway tracing and flux analysis in plant biochemistry and microbiology research.
• Quality control and impurity profiling in the manufacture of aspirin and other salicylate-based active pharmaceutical ingredients (APIs).

Quality Control

Our Salicylic Acid-13C6 is manufactured under strict quality systems to ensure exceptional isotopic and chemical purity, critical for reliable analytical results. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically ≥99 atom % 13C), chemical purity (by HPLC), and confirming identity via spectroscopic methods. We adhere to relevant standards for high-purity reference materials to support GLP and ISO 17025 compliant laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a dry environment. The product is hygroscopic (moisture-sensitive); ensure containers are sealed tightly after each use to prevent absorption of atmospheric moisture.
