2-HİDROKSİFOSFONOASETİK ASİT 
HPAA, esas olarak, çelik ve demir, petrokimya, enerji santralleri ve tıbbi endüstriler gibi alanlarda yağmurun doldurma suyu sisteminde katot korozyon inhibitörü olarak kullanılır. Çinko tuzu ile inşa edildiğinde, etki daha da iyi olur.
2-Hidroksi Fosfonoasetik Asit (HPAA) öncelikle su arıtımında, boru hattında ölçek engelleyici olarak kullanılır. 
HPAA ; 
A) yüksek korozyon suyu için uygun fosfonatlar arasında en iyi korozyon önleme kabiliyetine sahiptir;
B) çinko tuzu ile uyumludur;
C) iyi ısı kararlılığına, 200 ° C yüksek sıcaklık direncine sahiptir.
D) içeriğindeki düşük fosfor, çevreye daha az zarar verir.
HPAA, kimyasal olarak kararlıdır, hidrolize edilemez, asit veya alkali tarafından tahrip edilmesi zor, kullanımında emniyet, toksisite ve kirlilik içermez. HPAA çinko çözünürlüğünü artırabilir. Korozyon önleme kabiliyeti, HEDP ve EDTMP'den 5-8 kat daha iyidir. Düşük moleküllü polimerlerle yapıldığında, korozyon önleme etkisi daha da iyi hale gelir.
