    Methyl Orange Indicator

    C14H14N3NaO3S

    Product Overview

    High-purity methyl orange indicator for acid-base titrations.

    Detailed Description

    Methyl Orange Indicator supplier in Oman - Global Chemicals LLC provides high-quality methyl orange solution for analytical laboratories and educational facilities in Muscat, Sohar, Duqm, Salalah. Our methyl orange indicator changes from red (pH <3.1) to yellow (pH >4.4) making it ideal for strong acid-weak base titrations. The 0.1% aqueous solution provides sharp color change at endpoint. Widely used in university chemistry labs, water analysis facilities, pharmaceutical testing, and industrial QC across Oman. Essential for teaching acid-base chemistry and performing quantitative analysis. Methyl orange indicator solution (0.1% in water) is the standard indicator for titrations involving weak bases or mineral acid-strong base systems where the equivalence point falls in the acidic pH range (3.1–4.4 colour change: red to yellow). Used in Oman's QC and teaching labs for hydrochloric acid standardisation, carbonate/bicarbonate titrations in water analysis, and acid strength determination. Essential in industrial QC labs testing acid concentrations and in university analytical chemistry teaching. Global Chemicals LLC supplies methyl orange indicator as 0.1% aqueous solution in 100mL and 500mL dropper bottles, and as powder for custom solution preparation. CoA and SDS available.
