Description

Isopropyl-D7 Paraben is a deuterated isotopologue of isopropyl paraben, a compound widely used as a preservative. This deuterated version, with seven hydrogen atoms replaced by deuterium, is an essential analytical standard and tracer in advanced research and development. It is primarily utilized by scientists and quality control professionals in the pharmaceutical, cosmetic, and food industries. Its high isotopic purity makes it invaluable for mass spectrometry, metabolic studies, and ensuring regulatory compliance in product safety testing.

Application

• Internal Standard for Quantitative Analysis: Used in LC-MS and GC-MS methods for the accurate quantification of isopropyl paraben and related compounds in complex matrices.
• Metabolic Pathway Tracing: Serves as a stable isotope-labeled tracer in pharmacokinetic and drug metabolism studies to track the fate of parabens in biological systems.
• Method Development and Validation: Critical for developing and validating robust analytical methods in regulatory environments for pharmaceutical and cosmetic products.
• Quality Control Reference Material: Acts as a certified reference standard to ensure the accuracy and precision of preservative assays in finished goods.
• Environmental Fate Studies: Employed in research to understand the degradation, persistence, and transformation of parabens in environmental samples.
• Dermal Absorption Research: Used in studies investigating the penetration and absorption of parabens through skin in cosmetic and topical pharmaceutical formulations.
