UV spectrophotometric method development and validation of carbimazole in bulk and tablet dosage form

A new, simple, sensitive, precise, reproducible UV visible spectrophotometric method was developed for the estimation of Carbimazole in Tablet dosage form.

The UV spectrum of Carbimazole in methanol and distilled water (30:70) showed λ max at 289.6nm. Beer’s law is valid in the concentration range of 10-50μg/ml. This method was validated for linearity, accuracy, precision, ruggedness and robustness.

The method has demonstrated excellent linearity over the range of 10-50μg/ml with the regression equation y = 0.0232x + 0.0466, and regression coefficient i.e, r²= 0.9992 moreover, the method was found to be highly sensitive with LOD (1.818μg/ml) and LOQ (5.509μg/ml).

From the results it can be concluded that the given method can be successfully applied for assay of Carbimazole in Tablet dosage form.
