Folasaga
Meatotino: E maualalo le solubility i le vai ma lelei solubility i solubility organic. O ona vailaʻau e malosi ma e faigofie ona faʻaitiitia, alkylation ma isi gaioiga.
Fa'aaogā:
O le 2-hydroxy-3-nitro-5-chloropyridine o loʻo i ai le aoga faʻapitoa i le faʻaogaina o meaola. E mafai ona fa'aogaina e avea o se mea taua tele i le fa'aogaina o meaola ma e a'afia i le tele o gaioiga fa'aola, e pei o le tu'ufa'atasiga o mea fa'ato'aga o le hop.
Metotia:
E tele auala mo le saunia o le 2-hydroxy-3-nitro-5-chloropyridine, o le auala masani e maua mai i le nitrification o le 2-azacyclopentadiene, ona toe faʻaleleia atili lea o le hydrogenation ma le chlorination e maua ai le oloa faʻatatau.
Fa'amatalaga Saogalemu:
Aloese mai le faʻafesoʻotaʻi ma vailaʻau malolosi, vailaʻau malosi, alkali malosi ma isi mea e aloese ai mai faʻalavelave faʻalavelave.
Fa'alogo lelei i faiga puipuia a'o fa'aoga, ma fai mea e puipui ai le tagata lava ia, e pei o totigilima saogalemu, mata tioata, ma isi.
Pe a faʻaaoga pe teu, taofi le 2-hydroxy-3-nitro-5-chloropyridine i se nofoaga malulu, faʻaleleia lelei, mamao mai le afi ma le maualuga o le vevela.
