Fa'aaogāga

1. Pharmaceutical raw materials for the pharmaceutical industry: e talafeagai mo le masani ma le faʻamaʻaʻa o le manava, e maua i papa, suppositories ma isi ituaiga vailaʻau.

2. Phenolphthalein faʻaaogaina i le faʻaogaina o meaola: e masani ona faʻaaogaina mo palasitika gaosia, aemaise lava mo le faʻaogaina o le naphthyridine polyaryl ether ketone polyaryl ether ketone polymers.O lenei ituaiga polymer e sili ona lelei le vevela, faʻafefe vai, ma vailaʻau.Ona o lona tete'e o le corrosion, vevela matua tetee ma lelei faagasologa ma formability, alava, coatings ma mea composite faia mai ai e le o toe umi ae faaaogaina lautele i mea faaeletonika, masini masini, felauaiga, aerospace, atomic malosiaga inisinia ma fanua militeli.

3. Fa'aaoga le Phenolphthalein e fai ma fa'ailo fa'avae oona, fa'ailo mo le fa'avasegaina o vaifofo e le fa'afefeteina, ma le reagent mo su'esu'ega chromatographic.
