Description

o-Cresol-D7 is a deuterium-labeled isotopologue of ortho-cresol, a key compound in analytical chemistry and life sciences research. Its primary value lies in its use as a stable, non-radioactive internal standard for the precise quantification of o-cresol and related phenolic compounds via mass spectrometry. This high-purity labeled standard is essential for researchers and quality control laboratories in the pharmaceutical, environmental monitoring, and metabolomics fields, where accurate measurement is critical for method validation and regulatory compliance.

Application

• Internal Standard for GC-MS and LC-MS analysis of phenolic compounds.
• Quantitative analysis and method development in pharmaceutical impurity profiling.
• Metabolite tracking and pharmacokinetic studies in biomedical research.
• Environmental analysis for monitoring cresol isomers in air, water, and soil samples.
• Isotope dilution mass spectrometry (IDMS) for achieving high-accuracy results.
• Deuterium labeling studies in organic synthesis and reaction mechanism elucidation.
• Quality control and assurance in chemical manufacturing requiring trace analysis.

Quality Control

Our o-Cresol-D7 is produced under strict quality management systems to ensure the highest isotopic and chemical purity for analytical applications. Each batch is characterized by advanced spectroscopic and chromatographic techniques, including NMR, GC-MS, and HPLC. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >98 atom % D), chemical purity, and analytical results is provided with every shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This compound is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen or argon) is recommended to preserve stability and purity.
