Description

Acetic Anhydride (2,2'-13C2, 99%) is a stable isotope-labeled derivative of acetic anhydride, where two carbon atoms at the 2,2' positions are enriched with the carbon-13 isotope. This high isotopic purity of 99% is critical for applications requiring precise tracking and quantification in analytical and research methodologies. It is an essential reagent for scientists and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-quality labeled compounds for their processes.

Application

• NMR Spectroscopy: Used as an internal standard or chemical shift reference in nuclear magnetic resonance studies due to its distinct 13C signal.
• Metabolic Pathway Tracing: Employed in biochemical and pharmaceutical research to label and track acetate moieties in metabolic studies and drug metabolism investigations.
• Isotope Dilution Mass Spectrometry (IDMS): Serves as a high-purity standard for the accurate quantification of acetic anhydride or related compounds in complex matrices.
• Synthesis of Labeled Compounds: A key acetylating agent for introducing 13C-labeled acetyl groups into target molecules for research in medicinal chemistry and material science.
• Pharmaceutical Impurity Profiling: Utilized in the development and validation of analytical methods to identify and quantify process-related impurities.
• Polymer Chemistry Research: Used in the synthesis of isotopically labeled polymers to study polymerization mechanisms, kinetics, and polymer structure-property relationships.

Quality Control

Every batch of our Acetic Anhydride (2,2'-13C2, 99%) is produced and analyzed under strict quality management protocols. We ensure compliance with relevant industry standards for stable isotope-labeled compounds. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing key parameters including isotopic enrichment (by NMR or MS), chemical purity (by GC or HPLC), and identity confirmation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and highly volatile; ensure containers are kept tightly sealed when not in use to prevent moisture absorption and evaporation. Keep away from strong bases, oxidizing agents, and moisture.
