Description

2-Methylpropene-1-13C is a stable isotope-labeled analog of isobutylene, where the carbon-1 position is enriched with the carbon-13 isotope. This precise labeling is critical for advanced analytical and research applications requiring high specificity and traceability. It is an essential building block for researchers and manufacturers in the fields of pharmaceutical development, metabolic studies, and advanced material science.

Application

• Pharmaceutical Research & Development: Used as a labeled precursor in the synthesis of isotopically labeled active pharmaceutical ingredients (APIs) for pharmacokinetic, metabolic, and degradation pathway studies.
• Analytical Chemistry & Mass Spectrometry: Serves as an internal standard for quantitative analysis via GC-MS or LC-MS, improving accuracy in method development and validation.
• Metabolic Pathway Tracing: Enables the detailed tracking of carbon atoms in biological and chemical systems for fundamental research in biochemistry and plant science.
• Polymer Science: Acts as a labeled monomer or co-monomer in the development and analysis of specialized polymers, allowing for the study of polymer structure, kinetics, and degradation.
• Environmental & Geochemical Studies: Employed as a tracer in atmospheric chemistry models and studies of hydrocarbon fate and transport.
• NMR Spectroscopy: Provides a non-radioactive, sensitive probe for structural elucidation and dynamic studies of complex molecules in solution.

Quality Control

Every batch of 2-Methylpropene-1-13C is produced and analyzed under stringent quality protocols to ensure exceptional isotopic and chemical purity. Our quality assurance system includes verification of isotopic enrichment, chemical identity, and purity by advanced spectroscopic and chromatographic methods. A comprehensive Certificate of Analysis (COA) detailing isotopic purity (atom % 13C), chemical purity, and residual solvent levels is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and gaseous nature under standard conditions, this product is typically supplied in a sealed, pressurized cylinder or ampule. Store in a cool, well-ventilated area away from heat, sparks, and open flames. The container must be kept upright and secured. Use appropriate safety measures for handling compressed gases.
