ACS reagent, Dye content 85 %. Section 1 - Chemical Product and Company Identification . 114510. Because it changes colour at the pH of a midstrength acid, it is usually used in titrations for acids. Unlike a universal indicator, methyl orange does not have a full spectrum of color change, but it has a sharp end point. Methyl orange solution is a common pH indicator; it turns red at 3.2 pH & yellow at 4.4 pH. Synonyms: Methyl Orange, Modified; Methyl Orange-Xylene Cyanol . These products are applied extensively for microscopical staining and are also used for mixing with food colors as well as for cosmetic industry. 200 William Pitt Way . Principle: Sulphanilic acid with sodium carbonate converted into sodium salt of p-aminobenzene sulphonate, It undergoes diazotization reaction in presence of nitrous acid to form diazonium chloride salt. The method is suitable for all kinds of water with a pH value >4.3. 547-58-0 - STZCRXQWRGQSJD-GEEYTBSJSA-M - Methyl Orange - Similar structures search, synonyms, formulas, resource links, and other chemical information. CAS Number: 547-58-0. The methyl orange is dissolved in a weak buffer at a pH of 3.1, just below the equivalence point, so Because methyl orange is used as indicator, this value is also known as the m-value.
