《The colorimetric determination of molybdenum with polyhydric phenols》 was published in Talanta in 1962. These research results belong to Buchwald, H.; Richardson, E.. Computed Properties of C10H14O2 The article mentions the following:
Polyhydric phenols containing 2 ortho OH groups, such as catechol, 4-methylcatechol, 3,4-dihydroxybenzaldehyde, 3,4-dihydroxybenzoic acid, Tiron, gallic acid (I), pyrogallol, 2,3,4-trihydroxybenzoic acid, 3-methyl-6-sec-propyleatechol, 4-butylcatechol, 2,3,-dihydroxynaphthalene, and Na 2,3-dihydroxynaphthalene-6-sulfonate (II), can be used for the colorimetric determination of Mo. Beer’s law applies in the presence of a large excess of reagent:phenol (≳25:1). Dissolve the sample by fusion, mineral acid, or alkali. If Mo is reduced, oxidize it to Mo(VI) with HNO3, remove interfering ions (by ion exchange, changing the pH, etc.), adjust the soln, to contain 5-100 γ Mo/ml., adjust the pH to 5.2, dilute to 25 ml., measure the absorbance at 420 mμ, and compare with a calibration curve. Higher concns, can be determined with less accuracy at 500-600 mμ. The practical sensitivity for Mo is about 0.1 γ/ml. at 400 mμ. 15 references. The experimental part of the paper was very detailed, including the reaction process of 4-Butylbenzene-1,2-diol(cas: 2525-05-5Computed Properties of C10H14O2)
4-Butylbenzene-1,2-diol(cas: 2525-05-5) belongs to organoboron compounds. Organoboron compounds are versatile intermediates and as such are some of the most important classes of reagents in modern organic chemistry. Organoboron compounds are less toxic than organostannane reagents, and unlike alkynylzinc and magnesium, many organoboron compounds possess remarkable oxidative and thermal stabilities.
