Description

γ-Butyrolactone-13C4 is a stable isotope-labeled analog of γ-butyrolactone (GBL), where all four carbon atoms are the carbon-13 isotope. This high-purity labeled compound is essential for advanced analytical research, providing an internal standard for precise quantification and metabolic pathway tracing using techniques like NMR and mass spectrometry. It is a critical material for researchers and quality control laboratories in the pharmaceutical, agrochemical, and forensic science industries who require uncompromised accuracy in their spectroscopic analyses.

Application

• Internal Standard for Quantitative Analysis: Used in GC-MS, LC-MS, and NMR for the accurate quantification of γ-butyrolactone and related compounds in complex matrices.
• Metabolic Pathway Tracing: Enables the study of biochemical pathways and drug metabolism in pharmaceutical and biomedical research.
• Forensic Analysis and Toxicology: Serves as a reference standard in the detection and confirmation of GBL and its metabolites in forensic samples.
• Chemical Synthesis Research: Employed as a labeled building block in the synthesis of more complex 13C-labeled molecules for research purposes.
• Environmental Fate Studies: Facilitates tracking and analysis of GBL and its degradation products in environmental samples.
• Quality Assurance & Method Development: Critical for developing and validating highly accurate analytical methods in compliance with GLP and GMP guidelines.
