Diphenylene-4,4'-bisdiazonium hexafluorophosphate, also known as DPDHF, is a chemical compound with the molecular formula C12H10N4F6P2. It is a white crystalline solid that is soluble in water and serves as a precursor in the synthesis of various organic compounds, particularly in the preparation of diphenylene derivatives. DPDHF is formed by the reaction of diphenylene-4,4'-diamine with sodium nitrite and hydrochloric acid, followed by the addition of hexafluorophosphoric acid. diphenylene-4,4'-bisdiazonium hexafluorophosphate is widely used in the chemical industry for the production of dyes, pigments, and other specialty chemicals. Due to its reactivity, it is essential to handle DPDHF with care, following proper safety protocols to minimize potential hazards.

398-28-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 398-28-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,9 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.Calculate Digit Verification of CAS Registry Number 398-28:
(5*3)+(4*9)+(3*8)+(2*2)+(1*8)=87
87 % 10 = 7
So 398-28-7 is a valid CAS Registry Number.
