| Abstract | Formaldehyde has been highlighted as potential genotoxic impurity (GTI). Trace-level quantification of GTIs in drug substances requires sensitive, precise and accurate analytical methodologies for their estimation in drug substances and control. Analysis and estimation of formaldehyde is very challenging due to its properties namely volatility, high polarity, low molecular weight and over and above the absence of chromophore. This article presents a validated HPLC–UV method which is sensitive to quantification of formaldehyde in active pharmaceutical ingredient. As formaldehyde does not possess chromophore, the developed HPLC method involves derivatization with 2,4-dinitrophenylhydrazine. Using this method, the detection and quantitation limits achieved are 0.5 and 1.5 ppm, respectively. The calibration curve of formaldehyde was linear over the concentration range of 1.5–20 ppm. The method was found to be sensitive, precise and accurate and the proposed method has been successfully applied to estimate formaldehyde content in scale-up batches of bulk drug. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
