Ultramark 1621 (CAS 105809-15-2)
QUICK LINKS
Ultramark 1621 is a mixture of fluorinated phosphazines used as a reference compound for positive and negative ion fast-atom bombardment (FAB) high-resolution mass spectrometry. It is also a type of epoxy resin used as an embedding medium for electron microscopy samples like cells and tissues. This two-part resin consists of a resin and a hardener that are mixed together before use. Ultramark 1621 has several desirable properties that make it a popular choice for electron microscopy sample preparation. It has a low viscosity, allowing it to easily penetrate into small crevices and spaces within a specimen. It also has a relatively long pot life, giving researchers ample time to work with the resin before it sets. Once cured, Ultramark 1621 forms a hard, durable block that can be easily sectioned and mounted onto a microscope slide for imaging. It also has good resistance to chemical and thermal degradation, ensuring that samples remain stable during imaging and analysis.
