Used primarily as an intermediate in the synthesis of retinoids and vitamin A derivatives, this compound plays a role in pharmaceutical development, particularly in dermatology for skin treatment formulations such as acne and anti-aging medications. Its conjugated polyene structure makes it valuable in creating biologically active retinoid analogs that interact with retinoic acid receptors in the body. Additionally, it serves in research settings for studying cell differentiation and gene expression. Due to its light sensitivity and reactivity, it is handled under controlled conditions in the production of high-purity therapeutic agents.
