Uses

Different sources of media describe the Uses of 538-62-5 differently. You can refer to the following data:
1. Indicator
2. As a sensitive reagent for Hg, with which it gives a blue color.
3. It is a reagent for mercury determination.

Purification Methods

It crystallises from EtOH (ca 5mL/g), and dry the orange-red needles at 50o. A commercial sample, nominally sym-diphenylcarbazone (m 154-156o) was a mixture of diphenylcarbazide and diphenylcarbazone. The former was removed by dissolving 5g of the crude material in 75mL of warm EtOH, then adding 25g Na2CO3 dissolved in 400mL of distilled water. The alkaline solution was cooled and extracted six times with 50mL portions of diethyl ether (discarded). Diphenylcarbazone was then precipitated by acidifying the alkaline solution with 3M HNO3 or glacial acetic acid. It was filtered off, air dried, and stored in the dark [Gerlach & Frazier Anal Chem 30 1142 1958]. Other impurities are phenylsemicarbazide and diphenylcarbodiazone. Impurities can be detected by chromatography [Willems et al. Anal Chim Acta 51 544 1970]. It is used for detection and estimation of Hg, Zn, Cd, Cr, Cu, Fe and Mo [Cheng et al. Handbook of Organic Analytical Reagents, Boca Baton 277 1982, Beilstein 16 H 24, 16 IV 17.]

Check Digit Verification of cas no

The CAS Registry Mumber 538-62-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 538-62:
(5*5)+(4*3)+(3*8)+(2*6)+(1*2)=75
75 % 10 = 5
So 538-62-5 is a valid CAS Registry Number.

Rhodamine B degradation and reactive oxygen species generation by a ZnSe-graphene/TiO2 sonocatalyst

Zhu, Lei,Jo, Sun-Bok,Ye, Shu,Ullah, Kefayat,Oh, Won-Chun

, p. 1825 - 1832 (2014)

Nanostructured ZnSe-graphene/TiO2 was synthesized by a hydrothermal-assisted approach. ZnSe-graphene/TiO2 exhibited favorable adsorption of rhodamine B, a wide wavelength absorption range, and efficient charge separation. Reactive oxygen species were generated by the oxidation of 1,5-diphenyl carbazide to 1,5-diphenyl carbazone. The sonocatalytic reaction mechanism was proposed. These findings potentially broaden the applications of sonocatalytic technologies.

Solid state selective synthesis of diaryl carbazone

Xiao,Wang,Zhou

, p. 661 - 665 (2001)

The selective synthesis of diaryl carbazone using K3Fe(CN)6 as oxidant under alkaline condition in solid state is reported for the first time. Eight diaryl carbazone have been synthesized in excellent yields, and this method only needs cheap reagents, and simple procedure under mild condition.

Rapid synthesis of diaryl carbazone by N-bromosuccinimide and pyridine as the oxidation system

Wang, Yu-Lu,Duan, Zhi-Fang,Shi, Lei,Wang, Xiao-Yang,Li, Jian-Ping

, p. 423 - 428 (1999)

A new and rapid synthetic method of diaryl carbazone (ArN=NCONHNHAr) from aryl substituted carbazide is reported for the first time. Eight of the compounds were prepared by oxidation of aryl substituted carbazide using N- Bromosuccinimide and pyridine as the oxidation system in good yield under mild condition. This method only need simple instrument and short reaction time. A possible mechanism is suggested.

A facile preparation of graphene-based MxSy visible light driven photocatalyst and study of photochemically generating of oxygen species

Zhu, Lei,Sarkar, Sourav,Ye, Shu,Ullah, Kefayat,Meng, Ze-Da,Oh, Won-Chun

The as-synthesized graphene-MxSy (Sb2S3, MnS2, SnS) composites via a facile hydrothermal method efficiently catalyzed the photodegradation of methylene orange (MO) with high concentration in aqueous solutions under visible light irradiation. The generation of reactive oxygen species were detected through the oxidation reaction from 1,5-diphenyl carbazide (DPCI) to 1,5-diphenyl carbazone (DPCO). Based on the high photocatalytic activity, the graphene-SnS composite can be expected to be a practical visible light photocatalyst.
