Description

Monoisobutyl Phthalate-D4 CAS NO 1219802-26-2 is a deuterated isotopologue of monoisobutyl phthalate, where four hydrogen atoms are replaced with deuterium. This deuteration provides a stable, non-radioactive isotopic label, making it a critical internal standard for precise quantitative analysis in mass spectrometry. It is essential for researchers and quality control laboratories requiring high-accuracy measurements of phthalate esters and their metabolites. The compound is primarily utilized in analytical chemistry, environmental monitoring, and toxicology studies.

Application

• Internal Standard for GC-MS and LC-MS analysis of phthalate esters and their degradation products.
• Quantitative reference material in environmental testing for plasticizer contamination in water, soil, and air.
• Tracer compound in metabolic and pharmacokinetic studies within biomedical and toxicological research.
• Calibration standard for ensuring accuracy and compliance in regulatory testing of consumer products and food packaging.
• Critical reagent in the development and validation of analytical methods for phthalate detection.
• Use in stability studies and degradation pathway analysis of phthalate-based materials.
