CAS Number: 521-24-4
Molecular Formula: C10H5NaO5S
Molecular Weight: 260.20
IUPAC Name: Sodium 3,4-dioxo-3,4-dihydronaphthalene-1-sulfonate
Other Name: 3,4-Dihydro-3,4-dioxo-1-naphthalenesulfonic acid sodium salt, Folin’s reagent
Folin's reagent or sodium 1,2-naphthoquinone-4-sulfonate is a chemical reagent used as a derivatizing agent to measure levels of amines and amino acids. The reagent reacts with them in alkaline solution to produce a fluorescent material that can be easily detected.
The Folin reagent can be used with an acidic secondary reagent to distinguish MDMA and related compounds from PMMA and related compounds.
