Ko te waikawa 2-[4-(Dibutylamino)-2-hydroxybenzoyl]benzoic, e mōhiotia ana ko te BBA, he paura tioata kōwhai mārama.
1. Hanganga matū pumau me te pumau wera teitei, te ira rewa i te 190–193 °C, he pai mō te tukanga hanga pāmahana teitei;
2. He tino parakore, he iti te poke, he iti te makuku (te ngaronga i te whakamaroketanga ≤0.2%), he rite tonu te kounga o ia puranga;
3. Kei roto he rōpū mahi waikawa carboxylic, he ngāwari ki te whakahaere i ngā tauhohenga esterification me te condensation; he tino pai te tauhohenga hei takawaenga hanga matua;
4. He iti te piki me te heke i raro i ngā tikanga tukatuka noa, he pai te pumau o te rokiroki; ka āraihia te pirau i roto i te taiao hauhautanga me te maroke i te penapena hiri;
5. Kāore e wairewa i te wai, engari ka wairewa i roto i ngā whakarewa waro noa pērā i ngā waipiro, ngā ester me ngā whakarewa kakara.

Ko te BBA (CAS 54574-82-2) he takawaenga matua mō ngā tae leuco (ngā kaihanga tae) mō te pepa wera me te pepa tairongo-pēhanga.
1. Ngā Tae Tairongo Wera / Ahumahi Pepa Wera
Koinei te rauemi mata nui hei hanga i ngā tae pango leuco wera, e whakamahia whānuitia ana mō te pepa rīhiti wera, te pepa tapanga, ngā tīkiti rota, te pepa whakaahua, te pepa pire tekesi, me te pepa tā POS. He mārama te tae tā o te tae kua oti, he tere te whanaketanga o te tae, he ātete pai ki te mārama, ā, he mahi ārai-memeha.
2. Pepa Kore-Waro e Ārai ana i te Pēhanga
Whakamahia mō te hanga i ngā matū whakakōrohe mō te pepa tārua kore-waro, e tika ana mō ngā nama arumoni, ngā tuhinga kirimana, ngā puka paparanga-maha.
3. Matū Pai me te Tae Waenga
Whakamahia hei hanga i ētahi atu matū benzophenone kua whakakapia ki te amino, ngā tae waro, ngā rauemi mahi whatu.
