Description

Benzyl Salicylate-D4 CAS NO 1219802-40-0 is a deuterium-labeled isotopologue of benzyl salicylate, a key compound used as an internal standard in quantitative analytical chemistry. This high-purity, stable-labeled compound is essential for ensuring accuracy and reliability in mass spectrometry-based analyses, particularly in pharmacokinetic and metabolic studies. It is primarily utilized by research institutions, pharmaceutical developers, and analytical laboratories requiring precise quantification of benzyl salicylate or related compounds in complex matrices.

Application

• Internal Standard for LC-MS/MS: Serves as a critical reference compound for the accurate quantification of benzyl salicylate in biological samples (e.g., plasma, urine) and pharmaceutical formulations.
• Metabolite Tracing & Pharmacokinetics: Enables precise tracking of drug metabolism and absorption, distribution, metabolism, and excretion (ADME) profiles in preclinical and clinical research.
• Analytical Method Development & Validation: Used to develop, calibrate, and validate sensitive and specific liquid chromatography-mass spectrometry (LC-MS) methods.
• Quality Control in Pharmaceutical Manufacturing: Supports impurity profiling and assay verification of active pharmaceutical ingredients (APIs) and finished products containing salicylate derivatives.
• Forensic & Environmental Analysis: Aids in the detection and quantification of salicylate compounds in forensic toxicology and environmental monitoring studies.
• Stable Isotope Dilution Assays: Fundamental for isotope dilution mass spectrometry (IDMS), the gold-standard technique for achieving high metrological accuracy.
