Description

4-(2-Hydroxy-5-Methylphenylazo)Acetanilide-D3, n-[4-(2-Hydroxy-5-Methylphenylazo)Phenyl]Acetamide-D3 is a deuterium-labeled derivative of a key azo dye intermediate. This compound is essential for applications requiring high-purity, isotopically labeled materials for precise analytical and research purposes. It is primarily used by researchers and manufacturers in the pharmaceutical, analytical chemistry, and life sciences sectors for method development, internal standards, and tracer studies.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a deuterated internal standard in LC-MS/MS and GC-MS for the accurate quantification of its non-deuterated counterpart or related compounds in complex matrices.
• Metabolic Pathway Tracing: Employed in pharmaceutical and biochemical research to study the absorption, distribution, metabolism, and excretion (ADME) of azo-based compounds.
• Method Development and Validation: Serves as a critical reference material for developing and validating sensitive analytical methods in regulatory and quality control laboratories.
• Dye and Pigment Research: Acts as a labeled precursor or model compound in the research and development of novel azo dyes and pigments, allowing for detailed mechanistic studies.
• Pharmaceutical Impurity Profiling: Utilized as a standard to identify and quantify process-related impurities or degradation products in active pharmaceutical ingredients (APIs).
• Environmental Analysis: Applied as a tracer in environmental fate studies to monitor the breakdown and persistence of azo compounds.

Quality Control

Our deuterated compounds are produced under strict quality control protocols to ensure isotopic purity and chemical integrity. Each batch is characterized using advanced analytical techniques including NMR, HPLC, and Mass Spectrometry. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (D-atom %), chemical purity, and identity 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 place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
