|White to off White powder. Melt at about 220°C.
|Soluble in Acetone and in methylene chloride.
The Infra-red absorption spectrum of sample is concordant with that of the standard
The retention time of the sample solution corresponds to that of the standard solution, both relative to the internal standard as obtained in the assay.
