Chemical Properties: Nitidum cristallum purpureum vel pulveris rufo-brunneis.punctum liquescens 180-182 ℃.Solutum in ethanolo, acido glaciali acetico, in aqua fere solubili.
Usus: Methyl ruber est unus e indicibus acido-basi communibus adhibitis, solitus retrahitur solutio 0.1% ethanols, pH4.4 (rubrum) -6.2 (flava).Etiam in vivo protozoa maculavit.
Purpose: Protozoa vivum tingens;index acido-basi, coloratus pH 4.4 (rubrum) ad 6.2 (flavus);titratio ammoniaci, bases organicae et alkaloides infirmae, non autem acidi organicis aliis quam acido oxalico et picrico apto;componi potest cum Bromocresolo viridi et methylene caeruleo formam mixtam denotat, ad minuendum colorem mutandum et ampliandum suavitatem coloris mutationem emendare;adsorption indicator pro titratione praecipitatio, ut titratio fluoride ion cum nitrate thorio;determinatio liberae chlorini, chloritae et aliorum oxidantium
Utitur: protozoa live macula, acido-base indicator (pH4.4to6.2), serum orci dapibus diam test.PH color ambitus est 4.4 (rubrum) -6.2 (flavus).Titrate ammoniaci, bases organicae et alkaloides infirmae, non autem acida organica praeter acida oxalica et picrica.Coniungi potest cum bromocresolo viridi et methylene caeruleo ad formam mixti indicatorum minuendi colorem mutandi et emendandi suavitatem coloris mutationis.Indicatores adsorptiones pro titratione praecipitationis, ut titratione fluoride cum nitrate thorio.Determinatio liberae chlorini, chloritae et aliorum oxidantium.
