Description

Catechol-D4 is a deuterated isotopologue of catechol (1,2-dihydroxybenzene), where four hydrogen atoms are replaced with deuterium. This stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry, ensuring high analytical accuracy and reproducibility. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, environmental, and chemical analysis sectors for precise quantification of catechol and related phenolic compounds.

Application

• Internal Standard for Mass Spectrometry (MS): Critical for accurate quantification of catechol in LC-MS and GC-MS methods, correcting for instrument variability and sample preparation losses.
• Pharmaceutical Research & Metabolism Studies: Used in pharmacokinetic and metabolic pathway analysis to track the fate of catechol-containing drugs and their metabolites.
• Environmental and Food Safety Analysis: Enables precise measurement of catechol as a pollutant or natural product in complex matrices like water, soil, and foodstuffs.
• Chemical Synthesis & Process Development: Serves as a labeled starting material or tracer in the synthesis of deuterated polymers, antioxidants, or other advanced materials.
• Biomarker Research: Facilitates the sensitive detection and quantification of catecholamines and other biologically important phenols in clinical and diagnostic assays.

Quality Control

Every batch of Catechol-D4 is produced and analyzed under strict quality protocols to ensure exceptional isotopic purity and chemical integrity, suitable for sensitive analytical applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing isotopic enrichment (D atom %), chemical purity, and specific analytical results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its nature of being easily oxidized, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability.
