155174-21-3 Usage
General Description
2-Methylphenol, also known as o-cresol, is a chemical compound with the formula CH3C6H4OH. It is a colorless to yellowish liquid with a pungent odor, resembling that of creosote. It is commonly used in the production of disinfectants, pesticides, and pharmaceuticals. 2-Methylphenol is also a precursor to various industrial chemicals, including antioxidants, stabilizers, and dyes. It is considered to be harmful if swallowed, inhaled, or absorbed through the skin, and exposure to high levels can cause irritation to the respiratory system and skin. Therefore, it is important to handle and store 2-methylphenol with caution and in accordance with safety regulations.
Check Digit Verification of cas no
The CAS Registry Mumber 155174-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,1,7 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 155174-21:
(8*1)+(7*5)+(6*5)+(5*1)+(4*7)+(3*4)+(2*2)+(1*1)=123
123 % 10 = 3
So 155174-21-3 is a valid CAS Registry Number.

Stabilities of Substituted Benzyl Radicals: Dissociation Rates of Amino-, Hydroxy-, and Cyanoethylbenzenes
Suryan, M. M.,Stein, S. E.
, p. 7362 - 7365 (2007/10/02)
Rates of thermal unimolecular decomposition of amino-, hydroxy-, and cyanoethylbenzenes have been determined by the very low pressure pyrolysis technique.Assuming equal A factors, these rates, relative to the rate of dissociation of ethylbenzene, yield the following ortho, meta, and para, respectively, substituent effects on benzylic C-C bond strengths (kcal/mol): NH2, -2.7, -0.3, -1.7; OH, -1.7, -0.7, -1.1; and CN, -0.3, 0.4, -1.5.These effects are generally smaller than those for substituted anisoles and follow different trends.Along with the results of ESR studies of Nicholas and Arnold (Can.J.Chem. 1986, 64, 270), the present substituent effects indicate that a 1-G change in the benzylic hyperfine coupling constant corresponds to a 1.8 kcal mol-1 change in bond strength.
