For example, if I waned to make a calibration curve for calculating total phenols by Folin assay, I should use Gallic acid as a standard. that's what most papers say, but why to use Gallic acid not any other phenol??? and in general, on what basics do we say that a substance is a standard?

please, I want answers with references...ASAP.
