12026-57-2 Usage
Uses
Different sources of media describe the Uses of 12026-57-2 differently. You can refer to the following data:
1. Phosphomolybdic acid solution is a ready to use spray for visualization of steroids, alkaloids, antioxidants and terpenes resolved by thin layer chromatograpy (TLC) and high performance TLC (HPTLC). PMA is also a component of Masson′s trichrome stain.
2. Phosphomolybdic acid solution has been used in the preparation of supported phosphomolybdic acid membranes for use as superacid membranes for the oxidation of lighter alkanes in a catalytic membrane reactor.
3. For the detection of lipids, steroids, lactones, keto acids, hydroxy acids, unsaturated fatty acids, and phenolic compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 12026-57-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,2 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 12026-57:
(7*1)+(6*2)+(5*0)+(4*2)+(3*6)+(2*5)+(1*7)=62
62 % 10 = 2
So 12026-57-2 is a valid CAS Registry Number.

Vibrational investigations of polyoxometalates. 2. Evidence for anion-anion interactions in molybdenum(VI) and tungsten(VI) compounds related to the keggin structure

A systematic study of the cation-size effect on the vibrational spectra of α- and β-XM12O40n- polyoxoanions has been performed (X = BIII, SiIV, GeIV, PV, AsV; M = MoVI, WVI). The M-Od stretching frequencies decrease as the cation size increases. This is attributed to a weakening of anion-anion interactions of the electrostatic type. These interactions vanish for only interanionic oxygen-oxygen distances as long as 6 A? (tetrabutylammonium (TBA) salts). For these polyanions, the approximation for the isolated anion strictly holds with large counterions such as TBA. In addition, some preparations of polyanions are described for the first time.
