  • Applications

    Propanoic acid, 4-methylphenyl ester (CAS 7495-84-3), also known as 4‑methylphenyl propanoate or p‑tolyl propionate, is an aromatic ester with a sweet fruity–floral, slightly balsamic odor; it is used chiefly in perfumery to round accords, enhance diffusion, and improve substantivity in white‑floral (jasmine, ylang‑ylang), green, chypre, and soapy notes; in flavor and fragrance compounding it can add creamy/ripe‑fruit nuances at very low doses within applicable limits and serve as a high‑boiling odor carrier for personal‑care and detergent fragrances; in organic and cosmetic/pharmaceutical synthesis it functions as an intermediate/building block to tune hydrophobicity and odor persistence of related esters; in laboratories it is used as a reference standard and as a model substrate for studies of ester hydrolysis, acyl transfer, and catalytic kinetics, as well as a specialty solvent/co‑solvent in low‑polarity aromatic media; it may also be incorporated, at appropriate levels, as a scent‑modifying additive for plastics, printing inks, and varnishes; practical use should include formulation compatibility checks and compliance with current regulations/standards (e.g., IFRA, product safety, toxicology, and GHS/REACH labeling) in the target market.
