Phosphotungstic acid (PTA), a complex heteropoly acid with the chemical formula H3[PW12O40]·nH2O and CAS number 12501-23-4, is a compound of significant interest across various scientific and industrial sectors. Its unique chemical structure and resulting properties make it a valuable material for applications ranging from catalysis to advanced microscopy and biochemical analysis. For B2B buyers, understanding these characteristics is key to making informed purchasing decisions when looking to buy or source this essential chemical. As a premier manufacturer from China, we aim to provide clear insights into this versatile compound.

The defining characteristic of phosphotungstic acid is its strong acidity. As a heteropoly acid, it exhibits a high degree of proton dissociation, making it a potent Brønsted acid. This acidity is exploited in its role as a catalyst. PTA is effective in catalyzing a variety of organic reactions, including the hydrolysis of unsaturated hydrocarbons and the dehydration of alcohols. Its thermal stability further enhances its utility in processes requiring elevated temperatures. When seeking a reliable catalyst, specifying the desired purity and form of PTA from your supplier is critical.

In the realm of life sciences, phosphotungstic acid serves vital functions. In histology, it is a key component of stains like Phosphotungstic Acid Hematoxylin (PTAH), which is used to stain cellular components such as muscle fibers and connective tissue with distinct colors. The efficacy of these stains relies heavily on the purity and consistency of the PTA used. For electron microscopy, PTA acts as a highly effective negative stain due to its electron density. This property allows for the clear visualization of delicate biological structures like viruses and macromolecules, making it an indispensable reagent for imaging specialists.

Furthermore, phosphotungstic acid is recognized for its capability to precipitate proteins. This property finds application in biochemical assays and sample preparation, where the selective removal or concentration of proteins is necessary. Its effectiveness as a 'universal' precipitant for polar proteins under acidic conditions makes it a valuable tool in analytical laboratories. When sourcing for such applications, ensuring the material meets specific analytical standards is essential.
