Description

[13C]-9-Methylfluorene-9-Carbonyl Chloride CAS NO 1072315-89-9 is a stable isotope-labeled derivative of 9-methylfluorene-9-carbonyl chloride, where a carbon-13 atom is incorporated into the molecular structure. This labeling is critical for applications requiring precise molecular tracking and quantification, such as in mass spectrometry-based analytical methods. It is an essential building block and analytical standard for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require high-fidelity isotopic tracers for metabolism studies, environmental fate analysis, and reaction mechanism elucidation.

Application

• Isotopic Internal Standard for LC-MS/MS: Used as a quantitative internal standard in liquid chromatography-tandem mass spectrometry for the accurate measurement of its unlabeled counterpart or related metabolites in complex biological matrices.
• Pharmaceutical Research & Development: Serves as a key intermediate in the synthesis of carbon-13 labeled drug candidates for pharmacokinetic, pharmacodynamic, and absorption, distribution, metabolism, and excretion (ADME) studies.
• Metabolic Pathway Tracing: Employed in biochemical research to trace and quantify metabolic pathways and enzymatic activities in biological systems.
• Environmental Analysis: Acts as a labeled standard for detecting and quantifying environmental pollutants derived from fluorene structures in soil and water samples.
• Organic Synthesis Intermediate: Utilized in specialized organic synthesis where the introduction of a carbon-13 label is required for mechanistic studies or to create labeled polymers and advanced materials.
• Quality Control & Method Validation: Essential for developing and validating robust analytical methods in GMP and GLP environments, ensuring accuracy and regulatory compliance.
