CAS 27344-41-8

Tinopal CBS

Description:

Tinopal CBS, with the CAS number 27344-41-8, is a fluorescent whitening agent commonly used in various applications, including detergents, textiles, and paper products. It belongs to the class of stilbene derivatives and is characterized by its ability to absorb ultraviolet light and re-emit it as visible blue light, effectively enhancing the brightness and whiteness of materials. This compound is typically soluble in water and exhibits good stability under normal conditions, making it suitable for use in aqueous formulations. Tinopal CBS is particularly valued in laundry detergents for its ability to counteract yellowing and improve the overall appearance of fabrics. Additionally, it is non-toxic and environmentally friendly, which aligns with the increasing demand for sustainable chemical products. However, as with any chemical, proper handling and adherence to safety guidelines are essential to mitigate any potential risks associated with its use.

4,4'-Bis(2-sulfostyryl)biphenyl disodium

CAS: 27344-41-8

4,4'-Bis(2-sulfostyryl)biphenyl disodium (BSSPD) is a fluorescent dye that is used to measure the pH of wastewater. BSSPD shows a blue-green fluorescence in acidic solutions and a pink fluorescence in alkaline solutions. It has been shown that the use of BSSPD as an optical probe for wastewater can be used to detect changes in pH levels. This dye is also used to measure the degree of inflammation in the corneal epithelium by measuring the synchronous fluorescence. The effects of hydrochloric acid on BSSPD were studied and validated by optical properties and analytical methods.
