Ethyl-2-Methylbutyrate, with CAS number 7452-79-1, is a synthetic aroma chemical commonly used in perfumery for its fruity and sweet characteristics, reminiscent of apple and pear. It is often employed in fragrance compositions to enhance the fruity aspects of a scent, making it a popular choice in both fine fragrances and personal care products. Ethyl-2-Methylbutyrate typically sits in the top to middle notes of a formula, contributing to the initial impression of freshness and brightness. As a synthetic compound, it offers consistency in scent profile and stability, which is advantageous for formulators. While it is generally regarded as safe for use in cosmetics and fragrances, it is important for perfumers to be aware of any regulatory guidelines or restrictions that may apply, particularly in relation to IFRA standards. As with many synthetic aroma chemicals, it is advisable to use it within recommended usage levels to ensure safety and compliance in finished products. — AI-generated summary, 2026-09-02.
