Methyl Orange-Xylene Cyanol Solution In Water, Pure, Glass Bottle, 500ml

Reliable dual indicator solution for precise pH transition monitoring.

This Methyl Orange-Xylene Cyanol Solution is a ready-to-use laboratory indicator solution supplied in a secure 500ml glass bottle.

Manufactured by Thermo Fisher Scientific Chemicals, this formulation combines methyl orange and xylene cyanol to provide a defined, visually distinct pH transition range for analytical and research applications.

Intended Use & Applications

This solution is recommended for laboratory use and is supplied strictly for research purposes (RUO – Research Use Only).

It is suitable for pH monitoring, titration procedures, and analytical workflows that require a clear colour change within a specific acidic range.

The visual transition interval occurs from pH 3.2 (purple) to pH 4.2 (green), supporting accurate endpoint determination and dependable laboratory interpretation.

Chemical Composition & Physical Properties

With a molecular formula of C39H41N5Na2O9S3 and a molecular weight of 865.94g/mol, this solution presents as a dark blue-green liquid with an alcohol-like odour.

It is supplied as an aqueous solution and demonstrates stability under normal laboratory conditions. No specific reactivity concerns are known based on available information.

Safety Classification & Regulatory Status

This product is classified as non-hazardous according to the criteria of Safe Work Australia. No poison schedule number has been allocated.

It is not regulated for transport and does not contain substances listed under the Australian Illicit Drug Precursors/Reagents list or the National Code of Practice for Chemicals of Security Concern.

Handling Precautions & Storage Requirements

Appropriate personal protective equipment, including face protection, should be worn during handling. Ensure adequate ventilation and avoid contact with skin, eyes, and clothing. Ingestion and inhalation should be avoided.
