ASAS has years of experience in analysis and purification of butyl rubber oligomers.
The standards can be used for structure confirmation, method development, validation and quantitation as well as for in vitro tests like an AMES test. Sufficient amounts for OECD compliant AMES tests are available.
The standards are rigorously tested by an independent, GLP/GMP certified CRO (Spectral Service AG).
Identity is confirmed by 1H and 13C-NMR. The content of each batch is determined by quan-NMR.
