Products Description of Ethyl 2-Hydroxybenzoate 98% CAS#118-61-6
Ethyl salicylate appears as a colorless, oily liquid with a soft, subtle wintergreen-like scent. Its physical properties include a boiling point of 234℃ and a melting point of 1.3℃. The compound dissolves freely in ethanol, ether, acetic acid and most non-volatile oils, while only exhibiting slight solubility in water and glycerin.
This substance finds extensive application across multiple fields: it serves as a key material in organic synthesis, a core ingredient in flavor and fragrance manufacturing, and a functional solvent for diverse usage scenarios. It is synthesized via the esterification reaction between o-hydroxybenzoic acid (commonly known as salicylic acid) and ethanol, yielding a compound with highly valuable chemical properties suitable for both industrial production and academic research.

Product Application of Ethyl 2-Hydroxybenzoate 98% CAS#118-61-6
Under China's GB 2760-96 national standard, ethyl salicylate is granted provisional approval for use as an edible flavoring substance. Its primary applications cover the formulation of synthetic cinnamon oil, alongside a full range of berry-themed flavor systems — including blackberry, black currant, strawberry, raspberry and other matching fruity product formulations.
Beyond food use, ethyl salicylate is also a widely accepted ingredient in daily chemical goods. In soap fragrances, it imparts soft sweet floral undertones, and blends seamlessly with classic scent bases such as acacia, ylang-ylang and lily of the valley. For oral care items like toothpaste, it can be incorporated in low dosages to adjust and elevate the overall aroma and taste profile, acting as a viable alternative to fine-tune the sensory characteristics previously delivered by its methyl ester equivalent.
On top of these uses, ethyl salicylate functions as an effective solvent for nitrocellulose, fragrance raw materials and multiple organic synthesis workflows. It is extensively deployed as a core intermediate in organic synthesis, a foundational component in artificial flavor manufacturing, and a reliable material across a broad spectrum of industrial and chemical operations.
