β-Bromo-3-nitro-trans-cinnamic acid is a chemical compound with the molecular formula C9H6BrNO4. It is a derivative of cinnamic acid, featuring a bromine atom at the β-position (adjacent to the carboxyl group) and a nitro group at the 3-position (on the benzene ring). This organic compound exhibits a trans configuration, meaning the double bond between the carbon atoms is in the E-configuration. It is a pale yellow solid and is used in the synthesis of various pharmaceuticals and agrochemicals due to its unique structural properties. The presence of both a bromine atom and a nitro group in the molecule can lead to interesting reactivity patterns, making it a valuable intermediate in organic chemistry.

34875-23-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34875-23-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,7 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.Calculate Digit Verification of CAS Registry Number 34875-23:
(7*3)+(6*4)+(5*8)+(4*7)+(3*5)+(2*2)+(1*3)=135
135 % 10 = 5
So 34875-23-5 is a valid CAS Registry Number.
