1-Bromo-2-methyl-4-nitrobenzene

Description:

1-Bromo-2-methyl-4-nitrobenzene, with the CAS number 7149-70-4, is an aromatic compound characterized by the presence of a bromine atom, a methyl group, and a nitro group attached to a benzene ring. This compound features a bromine substituent at the first position, a methyl group at the second position, and a nitro group at the fourth position of the benzene ring, contributing to its chemical reactivity and properties. It is typically a yellow to brown solid at room temperature and is sparingly soluble in water but more soluble in organic solvents such as ethanol and acetone. The presence of the nitro group imparts significant electron-withdrawing characteristics, influencing the compound's reactivity in electrophilic substitution reactions. Additionally, 1-bromo-2-methyl-4-nitrobenzene can be used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Safety precautions should be taken when handling this compound, as it may pose health risks due to its bromine and nitro functionalities.

2-Bromo-5-nitrotoluene

CAS: 7149-70-4

2-Bromo-5-nitrotoluene is a monosubstituted aromatic compound with a pKa of -2.5. The hydroxyl group on the ring makes this compound acidic, and it will readily react with an electrophile to form an addition product. 2-Bromo-5-nitrotoluene undergoes reductive elimination to form 2-aminoethanol, which is more stable than the nitroso group. The mechanism of this reaction involves labile intermediates that are sensitive to light and heat. The frequency data for 2-bromo-5-nitrotoluene can be found in the table below: 2H NMR (400 MHz, CDCl) δ 7.60 (d, J=8 Hz, 1H), 7.50 (dd, J=8 Hz, 1H), 3.80 (s, 3H). 1H N
