The sensitizing capacity of 2,2(1)-dihydroxydiphenyl methane (2,2(1)-HPM), 4,4(1)-dihydroxydiphenyl methane (4,4(1)-HPM) and 2,4(1)-dihydroxydiphenyl methane (2,4(1)-HPM) was investigated with the guinea pig maximization test. These compounds are known contact sensitizers in phenol-formaldehyde resins. The study was performed to assess and compare their

Laser-induced fluorescence, single-vibronic level fluorescence (SVLF), UV hole burning, and fluorescence dip infrared (FDIR) spectroscopy have been carried out on bis-(2-hydroxyphenyl)methane in order to characterize the ground-state and first excited-state vibronic spectroscopy of this model flexible bichromophore. These studies identified

Stimulated emission pumping-population transfer spectroscopy (SEP-PTS) has been used to directly measure the energy threshold to isomerization between the two conformational isomers of bis(2-hydroxyphenyl)methane. These conformers have been shown in the preceding paper (DOI 10.1021/jp8098686) to be an OH...O H-bonded

16 patients with contact allergy to phenol-formaldehyde resins (P-F-R) were patch tested with 3 dihydroxydiphenyl methanes (bisphenol F). The chemical investigation by high pressure liquid chromatography indicated that the dihydroxydiphenyl methanes (HPM) were pure and separable. 9 patients reacted to
