Applications of 62758-12-7
| Industry | Application | Process |
|---|---|---|
| Analytical Chemistry | Acid-base titration indicator (pH transition range: 3.4–4.8; red → orange → yellow) | Dissolved directly in water or aqueous ethanol to prepare standard indicator solutions for endpoint detection in strong acid–weak base titrations |
| Textile Dyeing & Printing | Acid dyes for dyeing protein fibers such as wool and silk | Applied in a weakly acidic bath (pH 4–6), where dye uptake occurs via hydrogen bonding and van der Waals forces; acetic acid is added to adjust pH, with temperature controlled at 40–60°C |
| Biological Staining | Contrast staining of tissue sections and cell nuclei (commonly used in combination with methylene blue) | Employed in Heidenhain’s AZAN staining method (hematoxylin–orange G); processed through standard paraffin sectioning steps including fixation, deparaffinization, staining, differentiation, dehydration, and mounting |
| Food Testing | Reagent for diazotization–coupling colorimetric determination of nitrite content | After diazotization with sulfanilic acid, coupled with N-(1-naphthyl)ethylenediamine to form a magenta-colored azo dye for spectrophotometric quantification |
