Methyl Orange CAS: 547-58-0 | MF: C14H14N3NaO3S | MW: 327.33, Buy now for reliable and Reproducible results from Tristains indicators.

Methyl Orange (C.I. 13025) (CAS No. 547-58-0) is an organic azo dye that is well known to be used as a pH indicator. It has a red color in acidic media, it turns orange in a neutral environment, and turns yellow in an alkaline environment. Methyl Orange (C14H14N3NaO3S) is a compound with a very high solubility in water and alcohol and finds application in analytical chemistry, environmental testing, and in biological research. Specifically, this indicator dye is valued in its sharp and reliable color transition, which is the reason why it is a necessary reagent in the laboratory where pH-based assessment and chemical tests are performed.

Applications

  • Analytical Chemistry: Methyl Orange is normally utilized in showing the levels of pH below 3.1 and is reliable in titrations involving acidity and alkalinity.
  • Water Testing: It is used to check the pH changes in the course of environmental tests, drinking water tests, and wastewater tests.
  • Chemical Assays: The dye is used in the assays of oxalic acid and malonic acid, which show different color changes at certain concentration levels.

Key features

  • Distinct Color Transition: Exhibits red in acidic conditions and yellow in alkaline solutions
  • Water and Alcohol Solubility: The preparation of various laboratory protocols is easy.
  • Long Shelf Life: Can be stored in the laboratory over an extended period of time.
  • Flexible Applications: Applicable in the fields of biological, chemical and environmental studies.
  • Economical: Provides delectable quality at low prices.

General Description

Methyl Orange (CAS No. 547-58-0) is an artificial pH indicator dye that has been found to show a specific colorimetric change in color between red and yellow in acidic and alkaline ranges. In the case of laboratories that want reliable performance in terms of analysis, this indicator offers the best option for reliable and repeatable pH measurements. By having its typical orange color (C.I. 13025), Methyl Orange is an important part of titrations, monitoring of water quality, and biological staining because it is sensitive in the pH scale of about 3.0 to 4.0.

The use of high-purity Methyl Orange provided under the TriStains indicator range is essential by professionals in academic research, laboratories in industries, and environmental monitoring to achieve high standards of analysis. Bulk buying can be offered to encourage laboratories that need higher quantities at affordable costs. To ensure the conduct of pH, analytical, and biological staining, Methyl Orange (CAS No. 547-58-0) is a necessary reagent to be selected due to its accuracy, reliability, and adherence to laboratory standard operating procedures. See TriStains sales division or check the official platform to see the current prices and availability. Our Tristains indicators surely won’t disappoint as they are designed to meet the strictest requirements set forth by your laboratory’s standard operating procedures.
