A method is described for mass spectrometric analysis of a sample comprising phenolic OH, such as a steroid comprising a phenolic OH, using a quaternary amino oxy Cookson (QAOC) reagent. The QAOC reagent can improve ionization and fragmentation properties of phenolic OH samples, which can thereby improve quantitation and identification. The method can include derivatizing the phenolic OH sample with the QAOC reagent to create an adduct and analyzing the adduct using mass spectrometry. Derivatization of the sample can be a one-step reaction where the QAOC reagent comprises an aminooxy MS tag or can be a multi-step reaction, where the adduct is formed by the reaction of carbonyl substituted PTAD based reagent and the sample followed by combination with an aminooxy MS tag. The sample can also be enriched prior to reacting it with the reagent. The method can also allow for multiplexing.
