Picric acid, also known as 2,4,6-trinitrophenol, is a yellow crystalline solid that is highly explosive and has been historically used in the production of explosives and as a dye. It is a strong acid and can form salts with various bases. On the other hand, N,N'-dibutyl-formamidine picrate is a derivative of picric acid, where the picric acid molecule is combined with N,N'-dibutyl-formamidine. picric acid ; N,N'-dibutyl-formamidine picrate is used as a plasticizer and a stabilizer in various applications, particularly in the plastics industry. It is important to note that both picric acid and its derivatives can be hazardous due to their explosive nature and potential health risks, and they require careful handling and storage.
The CAS Registry Mumber 2303-93-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,0 and 3 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 2303-93: (6*2)+(5*3)+(4*0)+(3*3)+(2*9)+(1*3)=57 57 % 10 = 7 So 2303-93-7 is a valid CAS Registry Number.
