Description

Iso-Propyl 4-Hydroxybenzoate-2,3,5,6-D4 is a deuterated isotopologue of isopropylparaben, a widely used preservative. This compound is specifically designed for use as an internal standard in analytical chemistry, offering superior accuracy in quantitative analysis by minimizing interference from non-deuterated species. It is an essential tool for researchers and quality control laboratories in the pharmaceutical, cosmetic, and food industries who require precise measurement of paraben levels for safety and regulatory compliance.

Application

• Internal Standard for LC-MS/MS and GC-MS: Primary application for the accurate quantification of parabens and related compounds in complex matrices.
• Pharmaceutical Research & Development: Used in method development and validation for analyzing drug formulations and stability studies.
• Cosmetic Safety Testing: Enables precise measurement of paraben concentrations in creams, lotions, and other personal care products to ensure compliance with safety regulations.
• Food & Beverage Analysis: Employed in testing for preservative content and migration studies from packaging materials.
• Environmental Monitoring: Assists in tracing and quantifying parabens in water and soil samples for environmental impact assessments.
• Metabolomic and Biomarker Studies: Serves as a stable isotope-labeled tracer in metabolic pathway research.
