4-Pentylphenyl 4-methylbenzoate (CAS number 50649-59-7), with a chemical structure of 4-methylphenyl ester of 4-pentylphenyl, is a nematic liquid crystal. The only difference between 4-pentylphenyl 4-methylbenzoate and 4-pentylphenyl 4-methoxybenzoate is the latter has one more oxygen atom.

4-pentylphenyl 4-methylbenzoate can be employed as a matrix to form IBF2-matrix samples. Iodine-substituted difluoroboron(III) β-diketonate (BF2bdk) powders with 38 wt% iodine substituents show insignificant afterglow at 77 K. However, when doped into phenyl benzoate matrices, BF2bdk exhibits bright room-temperature phosphorescence with lifetimes of up to 1.0 s under ambient conditions.

4-pentylphenyl 4-methylbenzoate can also be used as a surrogate for the potency analysis of medical marijuana products.
