Description

2-Benzyloxy-Benzoic Acid-13C3 Benzyl Ester is a stable isotope-labeled compound, specifically a 13C3-labeled derivative of a benzyl-protected benzoic acid ester. This product is essential for use as an internal standard in quantitative mass spectrometry, enabling highly accurate and reliable analytical measurements. It is primarily needed by research institutions, pharmaceutical companies, and contract research organizations (CROs) engaged in advanced analytical chemistry, pharmacokinetic studies, and metabolic research.

Application

• Internal Standard for LC-MS/MS: Critical for precise quantification in bioanalytical methods for drug discovery and development.
• Metabolite Tracing & Pharmacokinetics (PK): Used in ADME (Absorption, Distribution, Metabolism, Excretion) studies to track drug metabolites.
• Stable Isotope Dilution Assays (SIDA): Provides high accuracy in quantifying target analytes in complex matrices like plasma, urine, or tissue homogenates.
• Biomedical Research: Supports proteomics and metabolomics research requiring isotope-coded affinity tags.
• Pharmaceutical Quality Control: Ensures accurate measurement of active pharmaceutical ingredients (APIs) and impurities.
• Environmental Analysis: Potential use in tracing specific organic compounds in environmental samples.
