Fluorescent whitening agent C.I.351 is commonly known as CBS, whose product quality and yield directly depends on the production control. The purification methods of 4,4′- bis(chloromethyl)- 1,1′- bi-phenyl (BCMB) and 4,4′- bis(diethoxy phosphomethyl) biphenyl (BPMB) were provided, and the liquid chroma-tography detection methods of BCMB, BPMB and CBS were also provided. These methods could be easily ap-plied in quality control of incoming materials and intermediates, as wel as tracking reaction process. It was al-so found that in order to obtain reddish CBS, the main impurity peak with the main peak area ratio must be less than 0.88.
