BENZIMIDAZOLONE RED - Introduction
4-[(4-oro-2-methoxyphenyl) azo]-N-(2,)-len, also known as the red basic dye 14:1, is an organic pigment. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: 4-[(4-chloro-2-methoxyphenyl)azo]-N-(2,)-is red crystalline powder.
-Solubility: 4-[(4-chroo-2-methoxyphenyl) azo]-N -2 (,)-is insoluble in water and soluble in organic solvents such as alcohols, ketones and aromatic hydrocarbons.
-Stability: 4-[(4-choro-2-methoxyphenyl) azo]-N-(2,)-calcium has good properties in terms of light and thermal stability, and is not easy to fade.
Use:
-Pigment: 4-[(4-choro-2-methoxyphenyl) azo]-N-(2,)-is used as a dye and pigment, and is widely used in paint, ink, plastic, rubber, textiles, Printing ink, etc.
-Indicator: 4-[(4-choro-2-methoxyphenyl) azo]-N-(2,)-It can also be used as one of the components of the acid-base indicator.
Preparation Method:
4-(4-chloro-2-methoxyphenyl)azo-N-(2, azo)-can be synthesized by introducing substituents on aniline compounds. Specific synthetic methods may vary by manufacturer and patent protection, so specific synthetic routes may vary.
Safety Information:
-Acute toxicity: 4-[(4-chroro-2-methoxyphenyl) azo]-N-(2,)-phenyl has low acute toxicity, but it is still necessary to avoid oral administration or inhalation.
-Skin contact: Prolonged or frequent contact may cause skin irritation. Protective gloves are recommended.
-Eye contact: It is very important to avoid entering the eyes. If in contact, rinse with water for at least 15 minutes and seek medical help.
-Inhalation risk: Avoid inhaling dust and operate in a well-ventilated area. If breathing difficulties occur, the patient should be moved to a fresh air area immediately, and if symptoms persist, seek medical help.
Although 4-(4-chroo-2-methoxyphenyl) azo-N-(2, azo) is considered a relatively safe chemical in industrial and commercial use, it is still recommended to take appropriate safety measures when handling, and store and dispose of it in accordance with relevant regulations. If necessary, please refer to the product's safety data form or consult the relevant professional.
