Uses

Different sources of media describe the Uses of 12501-23-4 differently. You can refer to the following data:
1. Phosphotungstic acid hydrate has been a useful histology stain for cell specimens.
2. 12-Tungstophosphate hydrate is used in histology as a component for staining of cell specimens. It binds to fibrin, collagen and fibers of connective tissues. It is also used to replace the anions of dyes from these materials. In solution, it acts as a homogeneous catalyst and involved in the hydrolysis of propene to give 2-propanol. It is supported with alumina and silica and act as a heterogeneous catalyst involved in the dehydration of 2-propanol to propene and methanol to hydrocarbons. In analytical chemistry, it is used to precipitate proteins and termed as "universal" precipitant for polar proteins.
3. Phosphotungstic acid hydrate may be used as a staining agent for the transmission electron microscope (TEM) imaging of cetyltrimethylammonium bromide (CTAB) coated gold nanorods.It may be used in the preparation of:Phosphotungstic acid doped ormosil hybrid networks.Niobia supported phosphotungstic acid (PTA) catalysts.Titanium dioxide (TiO2) nanoparticles /phosphotungstic acid (HPW) films.

General Description

Phosphotungstic acid hydrate is a heteropolyacid.

Flammability and Explosibility

Notclassified

Purification Methods

A few drops of conc HNO3 are added to 100g of phosphotungstic acid dissolved in 75mL of water, in a separating funnel, and the solution is extracted with diethyl ether. The lowest of the three layers, which contains a phosphotungstic acid-ether complex, is separated, washed several times with 2M HCl, then with water and again extracted with ether. Evaporation of the ether under vacuum with mild heating on a water bath gives crystals which are dried under vacuum and ground [Matijevic & Kerker, J Am Chem Soc 81 1307 1959].

Check Digit Verification of cas no

The CAS Registry Mumber 12501-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,5,0 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 12501-23:
(7*1)+(6*2)+(5*5)+(4*0)+(3*1)+(2*2)+(1*3)=54
54 % 10 = 4
So 12501-23-4 is a valid CAS Registry Number.
