  A novel fluorescent compound having a high light fastness, high fluorescence quantum yield and sharp absorption spectrum, which emits fluorescence having a wavelength in long wavelength region, as well as its use as a labeling agent, is disclosed. In Formula [I] below, by forming a specific hetero ring(s) with R 1 and R 2 , and/or R 6 and R 7 , shift of the wavelength of the fluorescence to longer wavelength and increase in molar extinction coefficient are attained maintaining the high light fastness, high fluorescence quantum yield and sharp absorption spectrum which the fluorescent dyes having the boron dipyrromethene skeleton have.

  The invention provides an aqueous solution capable of selectively protecting a nitrogen-containing silicon compound from corrosion by a treating solution for etching, cleaning or the like, etching oxygen-containing, carbon-containing silicon in particular, and making a large etch rate difference between a nitrogen-containing silicon compound and an oxygen-containing silicon compound, and a process for producing electronic parts as well. The invention is embodied by a treating solution for electronic parts that is an aqueous solution containing one or two or more of anionic surface active agents represented by the following formulae (1), (2) and (3), and a process for producing an electronic part. wherein R 1 , R 2 , and R 3 stands for hydrogen or an alkyl or alkylene group having 1 to 4 carbon atoms, and X 1 stands for a functional group capable of becoming an anionic ion. wherein R 4 stands for hydrogen or an alkyl or alkylene group having 1 to 4 carbon atoms, X 2 stands for a functional group capable of becoming an anionic ion, and n stands for a natural number of greater than 2. wherein R 5 stands for hydrogen or an alkyl or alkylene group having 1 to 4 carbon atoms, and X 3 , and X 4 stands for a functional group capable of becoming an anionic ion.
