| Abstract | Based on the absorption property of a diazine that can be formed by reaction of glyoxal and 3-methyl-2-benzothiazolinone hydrazone (MBTH) in the Ultraviolet-visible (UV-vis) spectral region, a HPLC method was developed for the determination of glyoxal in acetaldehyde solution. Glyoxal was derivatised from MBTH and the derivatives (diazine) were analyzed by HPLC for identification and quantification. The determination was performed on a ZORBAX Eclipse XDB-C18 column (4.6 × 250 mm, 5 μm) at 35°C with an injection volume of 10 μL, using a mixture of acetonitrile-water solvent (99:5, v:v) as a mobile phase with a flow rate of 0.8 mL·min$^{−1}$. The proper derivative reaction conditions were the temperature of 70°C, MBTH to carbonyl molar ratio of 12, and reaction time of 110 min. The glyoxal diazine was a yellow dye with a maximum molar absorptivity at 401 nm and its retention time was 5.2 min under optimal HPLC conditions. The standard curve for glyoxal had a strong linear relationship with a regression coefficient (R $_{2}$ = 0.999) in the range of 0.002–0.020 g·L$^{−1}$. The analysis of glyoxal in an oxidising solution gave accurate results with a relative standard deviation (RSD) value of 0.55%. The average relative recovery was 102%. This efficient HPLC technique is also proposed for detecting other dicarbonyl compounds besides glyoxal. |

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.
