(S)-(-)-3-Bromo-2-methylpropionic Acid Methyl Ester (S)-(-)-3-Bromoisobutyric Acid Methyl Ester 98190-85-3 B2140 Methyl (S)-(-)-3-Bromo-2-methylpropionate Methyl (S)-(-)-3-Bromoisobutyrate CAS 98190-85-3 chemical structure

Description

Structurally, (S)-(-)-3-Bromo-2-methylpropionic Acid Methyl Ester (S)-(-)-3-Bromoisobutyric Acid Methyl Ester 98190-85-3 B2140 Methyl (S)-(-)-3-Bromo-2-methylpropionate Methyl (S)-(-)-3-Bromoisobutyrate (C5H9BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 181.03 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
