The antibacterial drug compound of sulfanilamide is grown as a crystal by using the gel method. Here the sodium (Meta) silicate is used to form the silica gel as a growth medium for the crystal at room temperature. These crystals are characterized by single crystal XRD, powder XRD, FT−IR, FT−Raman, UV−Visible spectroscopy and SEM studies. The single crystal XRD study gives the information of cell parameters and structure of the molecule. The structure of this β-sulfanilamide molecule was already reported and discussed by many authors. But we are interested in the growth of sulfanilamide crystal from the gel medium. The cell parameter values of the grown crystals from the gel medium are exactly coinciding with the same crystal grown from the other methods. The powder XRD diffraction data also confirms the formation ofβ- sulfanilamide crystal. The FT−IR and FT−Raman spectroscopy studies confirm various functional groups present in the sulfanilamide molecule. From the UV−Visible spectroscopy study, the sulfanilamide crystal has a good transparency in the entire visible region. The lower cut−off wavelength is found to be at 312 nm. The band gap value of sulfanilamide crystal is 5.67 eV. The morphology of the grown crystal is identified from the SEM microphotograph
