CAS 106939-42-8: 2H-1,4-Benzoxazine, 7,8-difluoro-3,4-dihydro-3-methyl-, (3S)-

Description: 2H-1,4-Benzoxazine, 7,8-difluoro-3,4-dihydro-3-methyl-, (3S)-, with CAS number 106939-42-8, is a chemical compound characterized by its unique bicyclic structure that incorporates both benzene and oxazine rings. This compound features two fluorine atoms at the 7 and 8 positions, which can significantly influence its reactivity and physical properties, such as boiling and melting points. The presence of a methyl group at the 3-position contributes to its stereochemistry, specifically denoted as (3S), indicating the spatial arrangement of atoms around the chiral center. The dihydro configuration suggests that the compound may exhibit reduced aromatic character compared to fully aromatic derivatives, potentially affecting its stability and interactions with other molecules. Additionally, benzoxazines are known for their applications in materials science, particularly in the development of thermosetting resins and as intermediates in organic synthesis. Overall, the specific characteristics of this compound, including its fluorination and stereochemistry, make it of interest in various chemical and industrial applications.
