129-73-7 Usage

Chemical Properties

white to light brown, light green or light blue

Uses

Different sources of media describe the Uses of 129-73-7 differently. You can refer to the following data:
1. A metabolite of Malachite Green
2. For directly dyeing silk, wool, jute and leather; dyeing cotton after mordanting. Biological stain. Clinical reagent (inorganic phosphate assay). As spot test reagent for detecting sulfurous acid and cerium. As acid-base indicator: pH 0.0 yellow, 2.0 green; 11.6 green, 14 colorless.
3. Leucomalachite Green is a reagent for the quantitative colorimetric micro determination of hemoglobin and other heme compounds.

Purification Methods

Crystallise it from 95% EtOH (10mL/g), then from *benzene/EtOH, and finally from pet ether. [Beilstein 13 H 275, 13 II 89, 13 II 135, 13 III 529, 13 481.]

Check Digit Verification of cas no

The CAS Registry Mumber 129-73-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129-73:
(5*1)+(4*2)+(3*9)+(2*7)+(1*3)=57
57 % 10 = 7
So 129-73-7 is a valid CAS Registry Number.

Solvent-free synthesis of 4,4-diaminotriarylmethanes-leuco malachite materials in the presence of FePO4

Behbahani, Farahnaz K.,Khademloo, Elham

, p. 1507 - 1510 (2014)

A fast, efficient and versatile route for the synthesis of 4,4-diaminotriarylmethanes is reported using N,N-dimethyl aniline and aryl aldehydes in presence of FePO4 under solvent-free condition at 100°C.

The novel two step synthesis of CuO/ZnO and CuO/CdO nanocatalysts for enhancement of catalytic activity

Kumaraguru, K.,Sankaran, A.

, (2020)

In the present investigation, Copper oxide (CuO)/Zinc oxide (ZnO) and CuO/cadmium oxide (CdO) nanocomposites (NCs) were fabricated by a simple two-step process involving co-precipitation technique and hydrothermal approach for the first time. The Powder X-ray Diffraction (PXRD) pattern demonstrates the existence of monoclinic, hexagonal and cubic phase structure of CuO/ZnO and CuO/CdO NCs. The absorption spectrum of the material was obtained via UV–Visible Spectroscopy and the band-gap value is calculated using Tauc's relation as 1.7 eV, 2.8 eV and 2.75 eV respectively for pure, CuO/ZnO and CuO/CdO NCs. The FESEM images gave the spherical and stone-like morphologies in the prepared CuO/ZnO and CuO/CdO NCs. At room temperature, CuO/ZnO and CuO/CdO NCs act as superior catalyst for the reduction of Rhodamine B (RhB) and Malachite Green (MG) dyes and degradation efficiency attained to be 77.26%, 73.15% for RhB and 79.82%, 74.69 for MG, respectively.

Silver-catalyzed tandem 5- And 6-endo-cyclizationsviaconcomitant yne-ol-imine activation: selective entry to 2-aryldihydrofuroquinolines

Das, Prasanta,Karmakar, Swastik,Kundu, Sandip

, p. 16112 - 16118 (2021/09/22)

A silver(i) catalyzed domino imination-intramolecular biheterocyclization-aromatization cascade has been developed to construct 2-aryl/-heteroaryl dihydrofuroquinolines in moderate to good yield using an aldehyde and unprotected 4-(2-aminophenyl)but-3-yn-1-ol as precursors. Sequential Ag-(i)-induced 5-endo-digcyclization of the yne-ol part and 6-endo-trigcyclization of a proposed Ag-bound imine, followed by aromatization, furnish the furoquinoline derivatives.
