CAS 554-73-4

C.I. Acid Orange 5

Description:

C.I. Acid Orange 5, also known by its CAS number 554-73-4, is a synthetic azo dye primarily used in the textile industry for dyeing wool, silk, and nylon. It exhibits a vibrant orange color and is characterized by its solubility in water, making it suitable for various applications in aqueous solutions. The chemical structure of Acid Orange 5 features an azo group (-N=N-) which is responsible for its color properties. This dye is known for its good lightfastness and moderate washfastness, although its stability can vary depending on the conditions of use. In addition to textiles, Acid Orange 5 is also utilized in food and cosmetic applications, although its use in food is subject to regulatory scrutiny in many regions due to potential health concerns associated with azo dyes. Safety data indicates that while it may cause irritation upon contact with skin or eyes, it is generally considered to have low toxicity. Proper handling and disposal are recommended to mitigate environmental impact.

Orange IV is a surfactant that is used to remove nitrogen from wastewater. It has been shown to be effective in removing nitrogen from wastewater, and can be used as a substitute for sodium dodecyl sulfate (SDS). Orange IV has been shown to have similar properties as SDS, but does not contain any sulfur atoms. This surfactant has been shown to have less of an effect on the ph of the water being treated, and can be considered for use in natural water where the ph is already acidic. The surface methodology for this surfactant includes flow assay, which uses fluorescence spectrometry and synchronous fluorescence. Fluorescence spectrometry involves measuring the amount of light emitted by a substance when irradiated with light of a certain wavelength. Synchronous fluorescence involves using two lasers with different wavelengths to measure how quickly or slowly molecules react with each other. In this case, it measures how quickly or slowly Orange IV reacts with other substances in order to determine
