Description

Benzilic-D10 Acid (Rings-D10) is a high-purity, deuterium-labeled derivative of benzilic acid, where all ten hydrogen atoms on the aromatic rings are replaced with deuterium (CAS NO 1219799-12-8). This isotopic labeling is critical for applications requiring non-radioactive tracers and internal standards in advanced analytical techniques. It is an essential building block for researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors who require precise metabolic and pharmacokinetic studies.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a stable, non-radioactive isotopic internal standard in LC-MS and GC-MS analysis for the accurate quantification of benzilic acid and related compounds in complex matrices.
• Pharmaceutical Research & Development: Used as a deuterated precursor or tracer in the synthesis of labeled drug candidates to study Absorption, Distribution, Metabolism, and Excretion (ADME) properties.
• Metabolic Pathway Tracing: Enables detailed investigation of biochemical pathways and metabolite identification without interference from endogenous compounds.
• Analytical Reference Standard: Provides a certified reference material for method development, validation, and quality control in analytical laboratories.
• Agrochemical Studies: Employed in environmental fate studies and residue analysis of pesticides or herbicides where benzilic acid is a metabolite.
• NMR Spectroscopy Solvent: Can be utilized as a specialty solvent or shift reference in deuterium NMR spectroscopy due to its specific isotopic signature.

Quality Control

Every batch of Benzilic-D10 Acid (Rings-D10) is manufactured and analyzed under strict quality management systems. We provide comprehensive Certificates of Analysis (COA) detailing isotopic purity (D-enrichment), chemical purity by HPLC, and identity confirmation by NMR and MS. Our products are suitable for use as high-grade analytical and research standards, ensuring reliability and reproducibility in sensitive applications.

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 compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
