Dansyl-gamma-Amino-n-Butyric Acid Cyclohexylammonium Salt is a fluorescent dansyl derivative of gamma-aminobutyric acid supplied as the cyclohexylammonium salt. CAS 76563-43-4 is consistently indexed under the gamma-amino name.
This distinction matters because gamma-aminobutyric acid does not contain the alpha stereocenter implied by an R/S amino-acid label.

Why the Cyclohexylammonium Salt Is Part of the Identity
The dansylated acid is paired with cyclohexylammonium, giving the reported formula C16H20N2O4S·C6H13N and total molecular weight 435.58 g/mol. Salt form can affect solubility, handling and analytical retention, so a free-acid mass should not be substituted for the salt-form specification.
Analytical and Fluorescence Use
The dansyl group provides a strong chromophore/fluorophore useful in analytical workflows. Current chromatography resources also index UV-Vis and HPLC applications for this compound. We consider wavelength selection, solvent composition and salt state important experimental variables because each can influence retention and signal intensity.
Relationship to Other Dansylated Amino-Acid Probes
This GABA-derived compound is chemically distinct from Dansyl-L-proline and Dansyl-L-Leu-OH. Those products contain chiral alpha-amino-acid scaffolds, whereas the gamma-aminobutyric-acid derivative has different backbone topology and should not be assigned their protein-binding behavior without data.
Procurement and QC Considerations
Confirm CAS 76563-43-4, total formula C22H33N3O4S, MW 435.58 g/mol and the cyclohexylammonium salt structure. Public supplier documentation reports a solid, partial water solubility and desiccated -20 C storage.

Frequently Asked Questions
Why is cyclohexylammonium included in the formula?
It is the counterion of the dansylated carboxylate and is part of the isolated salt form.
Is this the same compound as Dansyl-L-proline?
No. Both contain a dansyl fluorophore, but their amino-acid/backbone structures and salt forms are different.
