Description

Hydrocinnamic-D9 Acid is a high-purity, deuterium-labeled isotopologue of hydrocinnamic acid, where nine hydrogen atoms are replaced by deuterium. This compound is essential as a stable isotope-labeled internal standard for precise quantitative analysis in mass spectrometry-based applications. It is primarily used by researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental science sectors to ensure accurate measurement of hydrocinnamic acid and related metabolites.

Application

• Internal Standard for LC-MS/MS: Critical for the accurate quantification of hydrocinnamic acid and its derivatives in complex biological matrices like plasma, urine, and tissue homogenates.
• Pharmaceutical Metabolism Studies: Used in pharmacokinetic (PK) and pharmacodynamic (PD) research to track drug metabolism and bioavailability.
• Biochemical Research: Serves as a tracer in metabolic pathway analysis and enzymatic studies involving phenylalanine metabolism.
• Food and Flavor Analysis: Enables precise measurement of hydrocinnamic acid, a natural antioxidant and flavor precursor, in food products and beverages.
• Environmental Monitoring: Assists in the detection and quantification of phenolic pollutants in environmental water and soil samples.
• Synthetic Intermediate: Used in the synthesis of deuterium-labeled fine chemicals, fragrances, and advanced materials for research purposes.
