(+/-)-p-menth-1-en-7-al-(2,4-dinitro-phenylhydrazone) is a complex organic compound derived from p-menthane, a bicyclic monoterpene found in essential oils. (+/-)-p-menth-1-en-7-al-(2,4-dinitro-phenylhydrazone) is formed by the reaction of p-menth-1-en-7-al, an aldehyde, with 2,4-dinitrophenylhydrazine, a reagent used for the detection and identification of aldehydes and ketones. The resulting product, a hydrazone derivative, is characterized by the presence of a 2,4-dinitrophenyl group attached to the aldehyde's carbonyl carbon through a hydrazone linkage. This chemical is often used in analytical chemistry for the qualitative detection of aldehydes and ketones, as the formation of the colored hydrazone derivative aids in their identification.
The CAS Registry Mumber 2153-65-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,5 and 3 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2153-65: (6*2)+(5*1)+(4*5)+(3*3)+(2*6)+(1*5)=63 63 % 10 = 3 So 2153-65-3 is a valid CAS Registry Number.
