Thermal analysis and validation of UV and visible spectrophotometric methods for the determination of new antibiotic tigecycline in pharmaceutical product
(Scientific & Academic Publishing, 2012)
This work has proposed the development and validation of ultraviolet (UV) and visible spectrophotometric methods for determination of tigecycline in lyophilized powder. In UV method tigecycline showed absorption maximum ...
Spectrophotometric determination of dipyrone in pharmaceutical preparations by using chromotropic acid
(Elsevier B.V., 1999-09-30)
A spectrophotometric method for the determination of dipyrone in pharmaceutical preparations is proposed. This method is based on selective oxidation of dipyrone, in the presence of sulphuric acid, splitting off formaldehyde ...
