3α,11β-dihydroxy-5α-androstan-17-one-(2,4-dinitro-phenylhydrazone) is a complex organic compound derived from the androstane steroidal structure. It is characterized by the presence of two hydroxyl groups at the 3α and 11β positions, and a ketone group at the 17-one position. The 2,4-dinitro-phenylhydrazone moiety is a derivative formed by the reaction of the ketone group with 2,4-dinitrophenylhydrazine, which is used to form a stable hydrazone adduct. This chemical modification can enhance the solubility and stability of the steroid, and is often employed in analytical chemistry for the detection and quantification of ketone-containing compounds. The compound plays a role in various biological processes and can be found in the context of steroid analysis, pharmaceutical research, and endocrinology.
The CAS Registry Mumber 4705-59-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 5 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4705-59: (6*4)+(5*7)+(4*0)+(3*5)+(2*5)+(1*9)=93 93 % 10 = 3 So 4705-59-3 is a valid CAS Registry Number.
