DescriptionECHEMI Editorial ReferenceBenzyl (3R,4S)-3-(2-bromoacetyl)-4-ethyl-1-pyrrolidinecarboxylate is extremely sensitive to pH, and the color characteristics of benzyl (3R,4S)-3-(2-bromoacetyl)-4-ethyl-1-pyrrolidinecarboxylate vary considerably at different pH values, and it exists and exhibits a red color mainly in the form of a molten salt ion when the aqueous pH is below 2, and it exhibits a red color when the pH is in the weak acidic range. pH is in the weakly acidic range, benzyl (3R,4S)-3-(2-bromoacetyl)-4-ethyl-1-pyrrolidinecarboxylate exists in the form of a colorless methanolic pseudobasic or hemiacetal form, and as the aqueous solution progressively approaches neutrality, benzyl (3R,4S)-3-(2-bromoacetyl)-4-ethyl-1-pyrrolidinecarboxylate deprotonates to a quinone base, and may also ring-open to the chalcone form.Basic Info
