Abstract:
In the title compound, C14H15BrN2O2S, synthesized by the reaction of the corresponding phenacyl thio-cyanate with morpholine, the dihedral angle between the 1,3-thia-zole ring and the phenolic substituent ring is 23.46 (10)° as a result of the steric influence of the ortho-methyl group on the thia-zole ring. A strong intra-molecular phenolic O-H⋯N hydrogen bond is present in the mol-ecule. In the crystal, a weak C-H⋯Ophenol hydrogen bond gives rise to chains lying parallel to [20-1]. A short inter-molecular Br⋯Omorpholine inter-action is also present [3.1338 (19) Å].

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
