Description

Butyric-4,4,4-D3 Acid is a stable isotope-labeled analog of butyric acid, where three deuterium atoms replace the three hydrogen atoms on the terminal methyl group. This precise labeling makes it an essential internal standard and tracer in quantitative mass spectrometry and metabolic research. It is primarily utilized by analytical laboratories, pharmaceutical R&D departments, and academic institutions engaged in advanced biochemical studies.

Application

• Internal Standard for Quantitative Analysis (GC-MS, LC-MS)
• Metabolic Pathway Tracer and Flux Analysis
• Pharmaceutical Impurity Profiling and Degradation Studies
• Stable Isotope Labeling in Organic Synthesis
• Biomarker Discovery and Validation Research
• Nutritional and Gut Microbiome Metabolomics

Quality Control

Our Butyric-4,4,4-D3 Acid is produced under stringent conditions to ensure high isotopic purity and chemical integrity. Each batch undergoes rigorous quality testing, including isotopic enrichment analysis by NMR and chemical purity assessment by chromatography. Certificates of Analysis (COA) detailing isotopic purity (atom % D), chemical purity, and specific tests are available upon request to support your compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at room temperature (15-25°C). Due to its nature as a strong acid/organic solvent, keep away from incompatible materials such as strong bases and oxidizing agents.
