Although m-cresol shows predominant acidity, and so is mainly protogenic, its basicity is still appreciable (cf., Ka = 2 10 19) and therefore it belongs to Bronsted class 5 further, it shows excellent solubility for a wide range of organic compounds.

Besides the most important area of surface coatings, the use of photopolymers as photoresists in the manufacture of printed circuits is well established. Photoimaging with aryldiazonium salt photoinitiators and multifunctional cresol-novolac epoxides was first described by Schlesinger Crivello has mentioned several new photoresists based on the photopolymerization of epoxides with onium initiators Meier and Zweifel have shown that iron arene salts in combination with multifunctional cresol-novolac epoxides yield photoresists with high resolution and contrast. Dual functional epoxides (cf. Sect. 5) containing chalcone groups as light-sensitive units have been described as suitable photoresists especially... 

For bromthymol blue, J. T. Saunders finds, by comparison with Sorensen buffers, a salt error of — 0.19 when the medium is 0.6 N with respect to NaCl. The error becomes + 0.20 at a total electrolyte concentration of 0.003 N. The errors which Saunders finds for thymol blue, phenol red, cresol red, bromthymol blue, and bromcresol purple in salt concentrations below 0.1 N are in accord with the measurements of the author (cf. above pages 340 to 342). 

Fractionally distil it and add 2,6-di-tert-butyl-p-cresol ( 0.5%) to stabilise it. [Petrov et al. Doklady Acad Nauk USSR 93 293 7955, cf Chem Abstr 48 13616 1954, Beilstein 4 IV 3938.]...
