Quantification of urazole groups can be done by indirectly by determining the TAD groups on the gels. Titrating TAD groups against one of the reactants can be used for quantification. However, the titration method is prone to human error, as reactants take some time to diffuse deep into the gel. NMR analysis is a more reliable method to quantify TADs. A stock solution of a TAD reactive molecule can be reacted with a TAD gel to determine the TAD content of the gel. However, the target molecule should be chosen carefully. For example, furan has a low boiling point (30°C), and some of it could easily escape causing a positive error in TAD quantification. On the other hand, aniline gives 1:2 adducts with TAD that causes a negative error in quantification (ESI, Figure ,S4). Additionally, amine group of aniline can also decompose TAD over time that complicated analysis. to aniline, 1-naphthol also reacts with more than one TAD group. A reliable analysis could be done using 2-naphthol, as it a forms a 1:1 adduct with TAD (ESI Figure ). To determine the TAD content, three different batches of urazole potassium gels were oxidized using HNO3.
