DSBP, popularly known as Tinopal CBS-X, appears as a greenish yellow solid. It is used as an optical brightening agent for home care applications. It provides excellent white effects on cellulosic fibres over the whole temperature range, particularly from cold to medium working temperatures. It has a higher yield of whiteness than the traditional stilbene type brighteners. It finds wide applications in paper and pulp industry.

- Production of DSBP from 4,4- bis(chloromethyl) biphenyl
In this process, 4,4- bis(chloromethyl) biphenyl, obtained from the reaction between biphenyl and formaldehyde, is utilised to produce DSBP. 4,4- bis(chloromethyl) biphenyl is heated at a temperature between 117 and 119oC in the presence of trimethyl phosphite to give 4,4- bis(dimethoxyphosphonomethyl)biphenyl and methyl chloride, which finally reacts with benzaldehyde sulphonic acid to form DSBP.
