The Chemistry Department of Jai Hind College, Mumbai, is a popular center for education in chemistry. It started functioning from the inception of the college in 1949. It is one of the oldest and premier department in the city of Mumbai to have Post graduation (M. Sc. in Physical, Inorganic and Organic Chemistry). The strength of the department has been and continues to be excellence in teaching and research. The faculty of the department is extremely well qualified and motivated with a strong commitment towards teaching and research. The department is now actively pursuing research embracing both basic as well as the applied areas of chemistry.

The department which is over 60 years old has now grown and emerged as one of the progressive department in the city. It is one of the foremost and best in terms of the expertise and facilities available for applied and fundamental research.

As part of its academic activities the department organizes seminars, symposia, competitions, lectures by eminent researchers and scholars, industrial visits, workshops, etc. It also has the potential to undertake industrial consultancy projects and is in the process of collaborating in research projects in frontier areas with industries in India.

The department has played a pivotal role in establishing college’s reputation in Mumbai. Its faculty and students provide outstanding leadership in science and education. Our students are involved in various research projects in reputed industries, laboratories and intuitions in India and abroad and have won high level recognition. The spirit of pride in the tradition of chemistry is shared by generations of alumni, many of whom have become leaders in academics, industry development, corporates in India and Abroad.

A student who gets an opportunity to enter into our programme in this Department gets a glimpse of exciting education / research opportunity and an array of support facilities. Together these provide an environment for studies and research work in various fields that is amongst the best in the Country. Due to obvious reasons, students of high scholastic ability are attracted to the department. With the development of new building we plan to add further  M. Sc. by research in Organic & Inorganic Chemistry.

The department is committed to research which is reflected in the many number of minor/major projects sponsored by University of Mumbai, Industries and U.G.C. etc. carried by our able staff members. The research tradition is also reflected in the entire staff being doctorate holding a number of publications and patents.

With continued churning of scholars from this department, the department has lived up to its true potential and expectations. It is in the continuous process of introspection, evaluation and finding new avenues which will add further values to the standing of the department.
