Used in Optical Brightening Agents:
4,4'-Diamino-3,3'-biphenyldisulfonic acid is used as a key component in the manufacturing of optical brightening agents. These agents are added to various products such as textiles, plastics, and detergents to enhance their appearance by making them appear brighter and whiter.
Used in Environmental Applications:
4,4'-Diamino-3,3'-biphenyldisulfonic acid has been studied for its potential use in the treatment of leather industry wastewater. Its strong chelating and complexing properties make it a promising candidate for addressing environmental concerns related to water pollution.
It is crucial to handle 4,4'-diamino-3,3'-biphenyldisulfonic acid with care, as it can be harmful if ingested, inhaled, or comes into contact with skin. Proper safety measures should be taken during its production, use, and disposal to minimize potential health and environmental risks.
Check Digit Verification of cas no
The CAS Registry Mumber 3365-90-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,6 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3365-90:
(6*3)+(5*3)+(4*6)+(3*5)+(2*9)+(1*0)=90
90 % 10 = 0
So 3365-90-0 is a valid CAS Registry Number.

Anti-HIV achiral polyurea oligomers, a process for creating them, formulations using them, and their use in the treatment of AIDS
-
, (2008/06/13)
The present invention relates to achiral polyurea oligomers, their uses and formulations as anti-HIV pharmaceuticals and to a process for the preparation of narrow mono- and polydispersed oligomers as an emodiment of the invention. The achiral oligomers are derived from repeating units of the monomer 4,4'-diamino-biphenyl-3,3'-disulfonic acid and are water soluble, have a rigid backbone, possess ordered anionic spacing and have a number average molecular weight of 20,000. The process relates to the synthesis of narrow poly- and mono-dipersed oligomers comprising the steps of: 1) restricting the crude olydispersed anionic oligomer mixture to a narrow polydispersed anionic oligomer mixture to a narrow polydispersed anionic oligomer mixture; and/or 2) isolating the monodispersed anionic oligomer; and 3) optionally converting the narrow poly- or mono-dispersed anionic oligomer salt from Step 1 or 2 to a desired pharmaceutically-acceptable salt, especially a solim or potassium salt. The process steps may be executed whereby step 1 or 2 is done alone, each in combination with Step 3, or all three steps are done.
