The GHS information provided by 1 company from 1 notification to the ECHA C&L Inventory.
Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant & Hackh's Chemical Dictionary, 5th ed, p301, p499)

使用Fluorescamine is a non-fluorescent reagent that reacts readily under mild conditions with primary amines in amino acids and peptides to form stable, highly fluorescent compounds. Reaction takes place under mild conditions. Low background due to hydrolysis.
純化方法Fluram is a non-fluorescent reagent that reacts with primary amines to form highly fluorescent compounds. Purify it by dissolving (~1g) in Et2O/*C6H6 (1:1, 180 mL), washing with 1% aqueous NaHCO3 (50mL), drying (Na2SO4), and evaporating in a vacuum. Dissolve the residue in warm CH2Cl2 (5mL), dilute with Et2O (12mL) and refrigerate. Collect the solid and dry it in a vacuum. IR (CHCl3): 1810, 1745, 1722, 1625 and 1600 cm-1, and 1HNMR (CDCl3): 8.71 (s, -OHC=). [Weigele et max al. J Am Chem Soc 94 5927 1972, Weigele et al.
