For professionals in the chemical and manufacturing sectors, understanding the properties and applications of key additives is vital for optimizing product performance. Fluorescent Brightener 71 (CAS: 16090-02-1) stands out as a significant player in the field of optical brightening. This article provides an in-depth look at its characteristics and how to effectively source it.

Fluorescent Brightener 71 is chemically known by several synonyms, including disodium 4,4'-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)amino]stilbene-2,2'-disulphonate. Its molecular formula is C40H38N12Na2O8S2, with a molecular weight of approximately 924.91 g/mol. Typically supplied as a pale yellow solid, its primary function is to enhance the perceived whiteness and brightness of materials. This is achieved by absorbing ultraviolet light and re-emitting it as visible blue light, effectively neutralizing any yellowish tints that can develop in textiles, paper, and even certain detergent formulations.

The applications of Fluorescent Brightener 71 are primarily concentrated in industries where visual aesthetics are critical. In the textile industry, it's used to make fabrics appear whiter and more vibrant. In papermaking, it contributes to the high brightness and clean appearance of paper products, crucial for printing and packaging. Its ability to mask dullness makes it a valuable component for manufacturers aiming for premium product quality.
