Redox Indicators
Redox indicators are organic compounds and their solutions — such as ferroin, diphenylamine and its sulphonate, methylene blue, starch indicator and N-phenylanthranilic acid — that change colour at defined oxidation-reduction potentials to mark endpoints in redox titrations. Buyers in analytical, water-treatment, pharmaceutical, food and educational laboratories select them by transition potential, colour change and whether a dry powder or ready-to-use solution is needed, because the indicator's potential must match the titration system for a sharp endpoint.
Grades span laboratory reagent and analytical reagent (AR/ACS) for the solid indicators, plus standardised indicator solutions at defined concentration. Spec sheets characteristically cover dye content/assay, transition potential and colour change, moisture, and for solutions, concentration, solvent and stability. Many are supplied as low-percentage aqueous or alcoholic solutions ready for burette work. CAS and HS framing is provided on documentation rather than assumed here.
Forms include reagent bottles for powders and 100 mL to 1 L bottles for indicator solutions; alcohol-based solutions may carry flammable classification and are packed accordingly.
For EU import, REACH applicability for the indicator substances and CLP/GHS labelling are coordinated where required, with SDS supplied; flammable solution grades are assigned ADR/IMDG classes and UN numbers. SABER/SASO is coordinated for Saudi Arabia.
Himalay's verified manufacturer and exporter partners supply redox indicators with CoA per batch, SDS, REACH/CLP compliance coordinated for EU, GHS labelling, and SABER for Saudi Arabia handled as part of the standard order flow.
