It is a white crystalline solid that is soluble in water and slightly soluble in alcohol. Carbonylcyanidhydrazon is primarily used as a reagent in chemical analysis, particularly for the detection and determination of aldehydes and ketones. It forms a colored complex with these compounds, which can be used for their identification and quantification. Additionally, semicarbazide has been used as a precursor in the synthesis of various pharmaceuticals and agrochemicals. However, it is important to note that semicarbazide can be toxic and is classified as a hazardous substance, necessitating proper handling and disposal.
The CAS Registry Mumber 1618-10-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,1 and 8 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1618-10: (6*1)+(5*6)+(4*1)+(3*8)+(2*1)+(1*0)=66 66 % 10 = 6 So 1618-10-6 is a valid CAS Registry Number.
