Description

Heptanoic-D13 Acid CAS NO 130348-93-5 is a fully deuterated isotopologue of heptanoic acid, where all thirteen hydrogen atoms are replaced by deuterium. This high isotopic purity makes it an indispensable internal standard and tracer in quantitative mass spectrometry and NMR spectroscopy, ensuring analytical accuracy and reliability. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, agrochemical, and advanced materials sectors for metabolic studies, method development, and precise quantification.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a stable, non-interfering reference compound for the accurate quantification of heptanoic acid and related metabolites in complex biological matrices like plasma, urine, and tissue samples.
• NMR Spectroscopy Solvent & Tracer: Serves as a valuable deuterated solvent or chemical shift reference in nuclear magnetic resonance (NMR) experiments, aiding in structural elucidation and reaction monitoring.
• Pharmaceutical Research & Development: Critical in pharmacokinetic (PK) and pharmacodynamic (PD) studies, drug metabolism and disposition (DMPK) research, and the development of bioanalytical assays for regulatory submissions.
• Metabolomics and Biomarker Discovery: Enables precise tracking and quantification of fatty acid metabolism pathways in systems biology and clinical research aimed at identifying disease biomarkers.
• Chemical Synthesis of Labeled Compounds: Acts as a key deuterated building block for the synthesis of more complex isotopically labeled intermediates and active pharmaceutical ingredients (APIs).
• Environmental and Food Safety Analysis: Employed in trace-level detection and quantification of short-chain fatty acids in environmental samples and food products to ensure safety and compliance.

Quality Control

Every batch of Heptanoic-D13 Acid is produced and analyzed under strict quality management protocols to ensure the highest isotopic and chemical purity for critical research applications. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as isotopic enrichment (Atom % D), chemical purity, and identity confirmation. Our quality systems are designed to support compliance with cGMP and ISO 9001 standards where required for pharmaceutical and industrial use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its nature as a strong acid/organic solvent, keep away from incompatible materials such as strong bases, oxidizing agents, and reactive metals. For long-term stability, consider storage under an inert atmosphere.
