[Quantitative spectrophotometric determination of prodigiozan in the visible spectrum].
A procedure for quantitative determination of prodigiosan in 0.02 per cent solutions in the visible region of the spectrum is described. The procedure is based on the ability of prodigiosan to affect the spectral properties of 1-ethyl-2-[3-(ethylnaphthyl [1,2d]-thiazolin-3-imidine)-2methyl propenyl]-naphtho-[1,2d]-thiazolin bromide (a dye).
