CAS 89277-65-6

Formaldehyde-13C, homopolymer

Description:

Formaldehyde-13C, homopolymer, identified by CAS number 89277-65-6, is a carbon-13 isotopically labeled polymer derived from formaldehyde. This substance is characterized by its structural composition, where the carbon atoms in the polymer chain are predominantly the carbon-13 isotope, which is a stable isotope of carbon. The homopolymer is formed through the polymerization of formaldehyde, resulting in a polymeric structure that exhibits properties similar to those of conventional formaldehyde polymers, such as urea-formaldehyde or phenol-formaldehyde resins. Its unique isotopic labeling allows for applications in various fields, including analytical chemistry and nuclear magnetic resonance (NMR) spectroscopy, where it can be used as a tracer or in studies involving metabolic pathways. The polymer is typically a solid at room temperature and may exhibit varying degrees of solubility depending on its molecular weight and the presence of functional groups. Safety considerations include its potential irritant properties, necessitating appropriate handling and storage measures.
