(S)-(-)-2-bromo-1-α-methylbenzyl ka waiʻona he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

ʻAno maikaʻi:
(S)-(-)-2-bromo-1-α-methylbenzyl waiʻona he wai kala ʻole a ʻulaʻula paha me kahi ʻala kūikawā ma ka lumi wela. Loaʻa iā ia kahi ʻano ʻekolu-dimensional deformable e like me ia he hui chiral ʻo ia hoʻi, aia kahi kikowaena chiral ma ke axis o ka symmetry molekala.

Hoʻohana: Hiki ke hoʻohana ʻia ma ke ʻano he ligand no nā catalysts stereoselective.

Hanana:
Hiki ke loaʻa ke ʻano hoʻomākaukau o (S)-(-)-2-bromo-1-α-methylbenzyl alcohol ma ka hana ʻana i nā aldehydes a i ʻole ketones me ka thionyl bromide ma lalo o nā kūlana alkaline. Ma hope o ka hopena o ka hopena, pono ka hoʻokaʻawale ʻana o nā pūhui achiral a me ka hoʻomaʻemaʻe chiral o nā pūhui chiral.

ʻIke palekana:
Pono e pale ʻia ka pili ʻana me ka ʻili a me nā maka.
I ka wā o ka hana ʻana, pono e hōʻoia ʻia ka ventila maikaʻi e pale aku ai i ka inhalation a i ʻole ingestion.
Hiki ke hoʻoheheʻe ʻia ka pūhui i nā wela kiʻekiʻe e hana i nā kinoea ʻino, pono e mālama ʻia mai nā kumu ʻā a me nā wela kiʻekiʻe.
Pono e hoʻohana ʻia nā lako pale pilikino e like me nā mīkina lima lab a me nā maka makamae palekana i ka wā e hoʻohana ai.
Pono e mālama ʻia nā kūlana palekana a me nā kaʻina hana i ka lawelawe ʻana a me ka hoʻokuʻu ʻana.
Ma nā noi kūpono, pono e noʻonoʻo ʻia nā kūlana kikoʻī a me nā kūlana hoʻokolohua.
