Parotin, also known as potassium para-aminobenzoate, is a chemical compound with the formula C7H7KNO2. It is a white crystalline powder that is soluble in water and slightly soluble in ethanol. Parotin is primarily used as a preservative in the pharmaceutical industry, particularly in the formulation of ointments and creams, due to its ability to inhibit the growth of microorganisms. It is also used in the synthesis of other chemicals and as a reagent in various chemical analyses. The compound is generally considered safe for use in pharmaceuticals, but like any chemical, it should be handled with care to avoid potential health risks.
The CAS Registry Mumber 1392-81-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,9 and 2 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1392-81: (6*1)+(5*3)+(4*9)+(3*2)+(2*8)+(1*1)=80 80 % 10 = 0 So 1392-81-0 is a valid CAS Registry Number.
Ito(1954) reported that parotin A, the protein fraction prepared from the salivary gland, caused a fall in serum calcium. This claim has been investigated using a preparation made from human parotid saliva and a bio assay in rabbits. Animals fasted but given no injection or other treatment showe...detailed
