Organic synthesis: 4,4′- bischloromethyl diphenyl produced with diphenyl as the basic raw material is an important intermediate for synthesizing high-end fluorescent whitening agents of the totuylene diphenyl type.
Pharmaceutical intermediate: high-purity diphenyl is an important raw material for synthesizing pharmaceutical intermediates, 4,4′- -Bis(hydrox-ymethyl) diphenyl, diphenyl acetic acid, Flurbiprofen, and bifonazole.
Heat carrier: due to its high heat stability, diphenyl is an important raw material for producing SCHULTZ S740 (Biphenyl and diphenyl oxide) and SCHULTZ S730 (isopropyl diphenyl) heat transfer fluids.
LCD electronics: high-purity diphenyl is an important raw material used for preparing electrolyte, as well as for producing LCD intermediate 4- hydroxy -4’cyano diphenyl.
