Acid Red 260 - Names and Identifiers
Acid Red 260 - Introduction
Acid Red 260 is an organic synthetic pigment, also known as Acid Red 18. Its molecular formula is C20H13N2Na3O10S3, and it is often marked with "(C. I. 16255)" in its chemical name.
Acid Red 260 is a red powder, soluble in water. It exhibits a bright red color under acidic conditions and a change in hue under alkaline conditions. In addition, the pigment has good light resistance, temperature resistance and chemical resistance.
Acid red 260 is widely used in textile, leather, paper and ink industries as a dye and pigment. It can dye these materials, giving them a brilliant red color. In addition, acid red 260 is also commonly used in the production of silk, wool and nylon fiber dyeing agent.
Acid Red 260 is usually synthesized by a series of chemical reactions using sulfur compounds as raw materials. Specifically, the sulfur compound is first reacted with sodium nitrite to generate an m-nitro compound, and then the m-nitro compound is converted into an acid red 260 by an electrophilic displacement reaction.
Regarding safety information, acid red 260 is relatively safe for the human body under normal conditions of use, but the following matters still need to be paid attention. It may be irritating to the eyes and skin, so it is recommended to use appropriate protective measures during operation, such as wearing protective glasses and gloves. At the same time, avoid inhaling or ingesting the substance so as not to cause discomfort. If inadvertent contact or inhalation occurs, rinse immediately with plenty of water and seek medical assistance.
