Abstract: The title compound, C₁₇H₁₉BrO₅, bears an exo-orientated or R-configured 4-methoxyphenyl group and incorporates a C-O bond that is distinctly shorter than the three remaining acetal C-O bonds [1.415 (4) versus 1.431 (4)-1.448 (4) Å and 1.421 (4) versus 1.436 (4)-1.448 (4) Å for the two molecules in the asymmetric unit].
