Benzoin CAS 119-53-9

Benzoin is a white to light yellow crystal or powder with characteristic vanilla-almond aroma.It is mainly used as an intermediate in organic synthesis (e.g. diphenylethylenedione preparation), initiator of light-curing resins and traditional medicinal herbs (expectorant and anti-inflammatory), where its photosensitivity and antioxidant properties are prominent.It needs to be kept away from light and moisture and avoid contact with strong oxidising agents.
