Appearance: The appearance of potassium dihydrogen phosphate should be colorless tetragonal crystal or white crystalline powder. Therefore, if the appearance of the product is small crystal or crystalline powder, it is normal to judge the product.
Content The content of potassium dihydrogen phosphate (on a dry basis) is ≥92% for agricultural qualified products and ≥96% for agricultural first-grade products according to HG2321-92 standard, but most products currently in circulation in the market are marked ≥98%.
Please pay attention when purchasing: (1) The real authentic product should be marked with potassium dihydrogen phosphate content (dry basis) ≥98%, but not the total content of other various elements ≥98%, or other total substance content ≥98 % et confusing concept products. (2) Some products even have a potassium dihydrogen phosphate content of 98%, but in fact they are also unqualified products, because potassium oxide in the product is specified in the standard of potassium dihydrogen phosphate product (HG2321-92). The content (K2O) must satisfy: K2O ≥ 33.2%.
The price of genuine potassium dihydrogen phosphate is relatively high due to its high effective nutrient content. If the price is very low, the possibility of false product is very high. Please pay attention when purchasing.
