Hiki ke hoʻoheheʻe ʻia ka ʻōmaʻomaʻo Bromocresol i ka wai a hiki ke hoʻoheheʻe ʻia i ka ethanol, ether, ethyl acetate, a me benzene. Paʻa loa i ka alkali, huli ka ʻōmaʻomaʻo Bromocresol i kahi waihoʻoluʻu polū-ʻōmaʻomaʻo kūikawā i ka wā e hālāwai ai me nā ʻano wai wai alkaline. Hiki ke hoʻohana ʻia ka ʻōmaʻomaʻo Bromocresol ma ke ʻano he hōʻailona, e ʻike ʻia ka melemele ma ka pH 3.8 a me ka uliuli-'ōmaʻomaʻo ma ka pH 5.4.
