Description

4-Methyl-D3-Catechol is a deuterium-labeled derivative of 4-methylcatechol, a key intermediate in organic synthesis and analytical chemistry. This stable isotope-labeled compound is essential for creating internal standards in mass spectrometry, enabling highly accurate quantitative analysis in complex matrices. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and life science sectors for drug metabolism studies, environmental analysis, and advanced material synthesis.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a critical deuterated internal standard for the precise quantification of catechol derivatives and related metabolites in bioanalytical assays.
• Pharmaceutical Research & Development: Used in drug metabolism and pharmacokinetics (DMPK) studies to track and quantify parent compounds and their metabolites.
• Biochemical Tracer: Acts as a tracer in enzymatic and metabolic pathway studies due to its isotopic labeling, allowing for differentiation from endogenous compounds.
• Advanced Material Synthesis: A valuable building block for synthesizing deuterated polymers, ligands, and complex organic molecules for specialized applications.
• Environmental Analysis: Employed in the detection and quantification of phenolic pollutants and their degradation products in environmental samples.

Quality Control

Every batch of our 4-Methyl-D3-Catechol is produced and tested under stringent quality management protocols to ensure exceptional isotopic purity and chemical integrity. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as isotopic enrichment (D-atom %), chemical purity, and identity confirmation. Our quality assurance system is designed to meet the exacting standards required for analytical and research 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). Due to its sensitivity to oxidation, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended to maintain stability and purity.
