With all of the different pronunciations of this type of tip, and with my education being in biochemistry, I was curious to know if all of these types of tips are actually phenols or if there are various phenyls used in making these compounds. I know phenal is not a chemical compound, and I couldn't find anything under phenyl aldehyde either, so is there some different material that people are incorrectly calling phenalic, are there various types of phenyls being used, or do they just mean phenolic? Thanks in advance for any and all input you may be able to give.
