Abstract
A new simple, selective, rapid, precise reversed-phase high-performance liquid chromatography method has been developed and validated for the estimation of Molnupiravir in bulk and its pharmaceutical dosage form. The separation was made using Symmetry ODS C18 (4.6×150mm, 5µm) column. The mobile phase used contained Methanol. Phosphate Buffer pH-4.2 adjusted with Orthophosphoric acid solution in the ratio of 35:65% v/v in an isocratic mode at a wavelength of 236nm. The mobile-phase flow rate and the sample volume injected were 1 ml/min and 10 μL, respectively. The retention time of Molnupiravir was found to be 2.8 ±0.2mins. A good linear relationship of Molnupiravir r =0.999) was observed over a concentration range of 20 to 100µg/ml of Molnupiravir. The limit of detection (LOD) and limit of quantification (LOQ) for Molnupiravir was found to be 2.6µg/ml and 6.35µg/ml. The recovery percentage was observed in the range of 98-102%. The relative standard deviation for the precision study was found <2%. The developed method is simple, precise, specific, accurate and rapid, making it suitable for the estimation of Molnupiravir in bulk and marketed pharmaceutical dosage form. It was concluded that in the present developed RP- HPLC method is simple, rapid, and accurate, hence can be used for routine quality control analysis in the Pharmaceutical industry.

Also, all the figures and tables in the article must be original and the copyright permission of images must be prepared by authors. However, some articles may have flaws and have passed the journal filter, which dear authors may find fault with. Therefore, the editor of the journal asks the authors, if they see an error in the published articles of the journal, to email the article information along with the documents to the journal office.
CMBR Journal welcomes letters to the editor ([email protected], [email protected]) for the post-publication discussions and corrections which allows debate post publication on its site, through the Letters to Editor. Critical letters can be sent to the journal editor as soon as the article is online. Following points are to be considering before sending the letters (comments) to the editor.
[1] Letters that include statements of statistics, facts, research, or theories should include appropriate references, although more than three are discouraged.
[2] Letters that are personal attacks on an author rather than thoughtful criticism of the author’s ideas will not be considered for publication.
[3] There is no limit to the number of words in a letter.
[4] Letter writers should include a statement at the beginning of the letter stating that it is being submitted either for publication or not.
[5] Anonymous letters will not be considered.
[6] Letter writers must include Name, Email Address, Affiliation, mobile phone number, and Comments.
[7] Letters will be answered as soon as possible.
