Description

Paraformaldehyde (13C) is a stable, polymeric form of isotopically labeled formaldehyde, specifically enriched with the carbon-13 isotope at the carbonyl position. This labeled compound is essential for advanced research and analytical applications where precise molecular tracking is required. It is a critical reagent for scientists and manufacturers in the pharmaceutical, agrochemical, and life science industries, particularly for use in nuclear magnetic resonance (NMR) spectroscopy and as a tracer in metabolic studies.

Application

• NMR Spectroscopy & Structural Analysis: Serves as a key 13C-labeled building block for synthesizing isotopically labeled compounds used in complex structural elucidation and dynamic studies.
• Metabolic Pathway Tracing: Used in biochemical research to label and track the incorporation of one-carbon units in metabolic processes within living systems.
• Pharmaceutical Intermediate Synthesis: Employed in the research and development of novel Active Pharmaceutical Ingredients (APIs) where isotopic labeling is required for pharmacokinetic or mechanistic studies.
• Agrochemical Research: Utilized in the synthesis of labeled pesticide or herbicide intermediates to study environmental fate, degradation pathways, and mode of action.
• Material Science Research: Acts as a labeled precursor in the synthesis of specialty polymers and resins for advanced material characterization.
• Standards for Mass Spectrometry: Used in the preparation of internal standards for accurate quantification via LC-MS or GC-MS in complex matrices.
