2-Oxa-7-azaspiro[3.5]nonane hemioxalate

Spiro forms of oxazines find applications as leuco dyes, by frequently displaying chromism - reversibly interchanging between their colorless and colored forms. Spiro compounds are used as photo chromic materials. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
