Product Description: Thiofluor Chromatographic Grade
Thiofluor Chromatographic Grade is N,N-Dimethyl-2-Mercaptoethylamine Hydrochloride – Chromatographic Grade™ for Post-column Derivatization of Primary Amines
Primary amines form highly fluorescent adducts when reacted with o-Phthalaldehyde (OPA) and a mercaptan under basic conditions. The products of this reaction, 1-alkyl-2-thioalkyl-substituted isindoles, exhibit optimal excitation at 330 nm and maximal emission at 465 nm.
Pickering’s Thiofluor™, a solid, nearly odorless nucleophile, is a superior substitute for 2-Mercaptoethanol in the preparation of OPA reagents. It forms a more stable reagent and a longer-lasting fluorophore with OPA than does 2-Mercaptoethanol, yet it has the same fluorescence properties.
Unlike the volatile 2-Mercaptoethanol, Thiofluor™ will not migrate through the gas manifold and regulator of the OPA reagent pressurization system. Two grams of Thiofluor™ is equivalent to 1 mL of 2-Mercaptoethanol.
Thiofluor Chromatographic Grade is powered solid. The KayDee Tek part number is: KDT-3700-2000-N and it comes in a bottle of 10 grams.
KayDee Tek also carries these other reagents for post column methods.
