2,2,3,3,4,4-Hexafluoroglutaric anhydride (HFGA) is a colorless, crystalline compound with the chemical formula C6F6O3. It is a derivative of glutaric anhydride, where four hydrogen atoms are replaced by fluorine atoms. HFGA is a valuable intermediate in the synthesis of various fluorinated compounds, particularly in the pharmaceutical and agrochemical industries. It is known for its thermal stability, low toxicity, and high reactivity, making it a preferred choice for the preparation of fluorinated heterocycles, polymers, and other specialty chemicals. The anhydride's unique properties, such as its electron-withdrawing nature and its ability to participate in various chemical reactions, contribute to its utility in the synthesis of complex molecules with potential applications in medicine and materials science.
The CAS Registry Mumber 1547-74-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 7 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 1547-74: (6*1)+(5*5)+(4*4)+(3*7)+(2*7)+(1*4)=86 86 % 10 = 6 So 1547-74-6 is a valid CAS Registry Number.
