ʻO 2'-Hydroxyacetophenone kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

ʻAno maikaʻi:
- Ke ʻano: 2′-Hydroxyacetophenone he paʻa keʻokeʻo keʻokeʻo.

E hoʻohana:
- Hiki ke hoʻohana ʻia i ka hoʻomākaukau ʻana i nā hydroquinones a me nā mea hoʻomālamalama optical.

Hanana:
- 2′-Hydroxyacetophenone ka mea maʻamau i hoʻomākaukau ʻia e ka condensation reaction o benzoacetic acid a me iodoalkane.
- ʻO nā ʻano hana synthesis ʻē aʻe e pili ana i ka oxidation koho a me ka hydroxylation o ka acetophenone, a no ka acetophenone i pani ʻia, hiki ke hoʻomākaukau ʻia e ka esterification o nā phenols pili a me nā waikawa acetic.

ʻIke palekana:
- 2′-Hydroxyacetophenone he mea kemika a pono e mālama a mālama pono i mea e pale aku ai i ka pili ʻana me ka ʻili a me nā maka.
- Pono nā lako pale pilikino kūpono e like me nā mīkina lima lab, nā maka aniani, a me nā ʻaʻahu lab ke hoʻohana ʻia.
- I ka wā e mālama ai, pono e mālama ʻia i loko o kahi pahu paʻa i ka ea, ma kahi mamao aku i ka ʻā a me nā mea oxidants.
- I ka wā o ka mālama ʻana, pono e mālama ʻia e pale i ka hana ʻana o ka lepo a me nā mahu a me ka hōʻoia ʻana i kahi wahi hana maikaʻi.
