General description
Light Green SF Yellowish (LGSF) is an acidic triphenylmethane (TPM) dye with auxochromic and bathochromic groups, belonging to the class of polymethine dyes. It is frequently utilized as a histology stain for collagen. Commercial applications of the dye include its usage in cosmetics and personal care products. LGSF is also a permitted food colorant. Various studies indicate the toxicity of the stain and its adverse effects on the environment.
Application
Light Green SF Yellowish may be used as a reference dye:
- For the determination of fluoride in drinking water by spectrophotometric method.
- To determine its presence in foodstuff by high-performance liquid chromatography–diode array detection–ion trap time-of-flight tandem mass spectrometry.
