4-hydroxybenzaldehyde

4-Hydroxybenzaldehyde (CAS 123-08-0 ), commonly referred to as 4-HBA or p-hydroxybenzaldehyde, is a phenolic aldehyde used as a key synthetic intermediate and flavoring agent across pharmaceutical, food, and cosmetic manufacturing.

FEMA 3984 status supports its use in flavor applications where regulatory traceability is required. In pharmaceutical manufacturing, 4-HBA serves as a precursor in the synthesis of active ingredients.

It is used in the production of antiviral compounds and vanillin derivatives, making it a recurring procurement target for API producers. Food and beverage formulators source it as a flavoring component.

Its natural phenolic character contributes to vanilla-adjacent profiles in various food products. In personal care, it functions as a UV stabilizer and preservative booster in skin and hair formulations.

Polymer and resin producers also use it as a building block for UV-stabilizing additives and specialty antioxidant systems. 4-Hydroxybenzaldehyde is supplied as a white to off-white crystalline solid.

Standard commercial grades include technical and pharmaceutical-grade material, with high-purity specifications available to meet API intermediate requirements. FCC -grade material is available for flavor applications.

This grade is essential for food applications requiring documented food safety compliance. The material is handled according to strict quality protocols to ensure consistency across global supply chains.
