Identification
1st Identification A,C
2nd Identification A,B,D |
|
Melting point 75.0-78.0
By UV Exhibits 2 absorption maxima, at 264 nm and 272 nm. The ratio
of the absorbance measured at the maximum at 264 nm to that measured
at the shoulder at 258 nm is 1.20 to 1.30. The ratio of the
absorbance measured at the maximum at 272 nm to that measured at the
shoulder at 258 nm is 1.00 to 1.10.
By IR The infra-red absorbance spectrum obtained from the sample
should be concordant with spectrum obtained from the CRS.
By TLC The principal spot in the chromatogram obtained with the
test solution is similar in position, colour and size to the
principal spot in the chromatogram obtained with the reference
solution. |
