Description
Phosphomolybdic acid (PMA) is a versatile chemical compound known for its unique properties and wide range of applications across various industries. It is a heteropoly acid that forms a series of molybdenum oxide bronzes and is commonly used in the form of its hydrated form, phosphomolybdic acid solution.
Uses
Used in Chromatography:
Phosphomolybdic acid is used as a spray for visualization of various organic compounds, such as steroids, alkaloids, antioxidants, and terpenes, resolved by thin layer chromatography (TLC) and high-performance TLC (HPTLC). It aids in the detection and identification of these compounds by forming characteristic color complexes upon interaction with the compounds.
Used in Histopathology:
Phosphomolybdic acid is a component of Masson's trichrome stain, which is widely used in histopathology for the staining of connective tissues, such as collagen, reticular fibers, and muscle fibers. It helps in differentiating these tissues by imparting distinct colors, facilitating the examination and diagnosis of various pathological conditions.
Used in Catalysis:
Phosphomolybdic acid solution has been utilized in the preparation of supported phosphomolybdic acid membranes, which serve as superacid membranes for the oxidation of lighter alkanes in a catalytic membrane reactor. These membranes enhance the efficiency and selectivity of the oxidation process, making it a valuable tool in the petrochemical and chemical industries.
Used in Analytical Chemistry:
Phosphomolybdic acid is employed for the detection of various organic compounds, including lipids, steroids, lactones, keto acids, hydroxy acids, unsaturated fatty acids, and phenolic compounds. Its ability to form color complexes with these compounds allows for their identification and quantification, making it a valuable analytical tool in various research and industrial applications.
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.
