Objective: This study aims to estimate Resorcinol (3- hydroxy phenol). Methodology : The study was through the development of a simple and high sensitivity and selectivity to estimate Resorcinol (3- hydroxy phenol) and The method is based on the reaction of Resorcinol (3- hydroxyphenol) with Thiamine (Vitamin B ) and potassium Dichromate at pH 3.5. So The reactions gave an 1 intense water soluble color products that have maximum absorption at 510 nm. 4 -1 -1 Results: This study showed that the ε max for 3- hydroxy phenol is (0.145 Χ10 correlations (1-9 μg ml liter. Mol .cm ), A linear -1 ) for 3-hydroxyphenol compound was found between absorbance at λmax and concentration. The accurate (relative error was better than -0.2 %) and precise ( RSD was better than 1.2%). The colored product was found to be 1:1 (3-hydroxyphenol : Thiamine) . The stability constant of the reaction under 5 -1 optimized conditions at room temperature was 3.25 Χ10 L.mole . Recommendations: The study recommends the appointment of phenolic compounds or other phenolic derivatives are relying on this method any use of thiamine and oxidized worker himself (potassium dichromate). Key words: Thiamine, Resorcinol, potassium Dichromate, Spectrophotometry
