Uses
Used in Protein Studies:
1-ANILINONAPHTHALENE-8-SULFONIC ACID AMMONIUM SALT is used as a sensitive indicator for protein folding, conformational changes, and protein studies. It aids in understanding the structural and functional aspects of proteins through methodologies such as steady-state and dynamic fluorescence measurements.
Used in Engineering and Chemical Processes:
1-ANILINONAPHTHALENE-8-SULFONIC ACID AMMONIUM SALT is used as a component in the development of broad-spectrum tunable photoluminescent nanomaterials. These materials are constructed from modular light-harvesting platforms based on macrocyclic amphiphiles, which have potential applications in various industries.
Used in Dye Intermediates:
1-ANILINONAPHTHALENE-8-SULFONIC ACID AMMONIUM SALT is used as a dye intermediate for the manufacture of weak acid dark blue 5R and weak acid black BR, among other products.
Used in Cyclodextrin Inclusion Complexes:
1-ANILINONAPHTHALENE-8-SULFONIC ACID AMMONIUM SALT forms an inclusion complex with cyclodextrin, which is useful for mimicking biological recognition. The change in fluorescence of free-ANS to complexed-ANS can be measured to study these model systems.
Used in Sodium-Selective Fiber-Optic Sensors:
1-ANILINONAPHTHALENE-8-SULFONIC ACID AMMONIUM SALT is utilized in the reagent phase of a sodium-selective fiber-optic sensor. The reagent phase also contains a copper(II) polyelectrolyte, which binds to ANSA in the absence of sodium and quenches the fluorescence. In the presence of sodium, ANSA forms a cationic complex, creating ion-pairs and causing it to fluoresce.
Used in Di-Block Polymers:
1-ANILINONAPHTHALENE-8-SULFONIC ACID AMMONIUM SALT is often incorporated into di-block polymers and can be released by changes in the local environment, such as temperature and pH.
Used in Investigating Molecular Assemblies of Surfactants and Amphiphilic Polymers:
1-ANILINONAPHTHALENE-8-SULFONIC ACID AMMONIUM SALT is commonly used as a fluorescence probe to study molecular assemblies of surfactants and amphiphilic polymers. A blue shift of the emission maximum indicates that the fluorophore is located in less polar media.
Check Digit Verification of cas no
The CAS Registry Mumber 28836-03-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,8,3 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28836-03:
(7*2)+(6*8)+(5*8)+(4*3)+(3*6)+(2*0)+(1*3)=135
135 % 10 = 5
So 28836-03-5 is a valid CAS Registry Number.
