Geranial

Geranial (CAS 141-27-5), also known commercially as trans-citral or lemonal, is the trans-isomer of citral and the primary contributor to the intense lemon character found in citral mixtures. It functions as a key aroma chemical and flavoring agent, and serves as a synthetic precursor in the production of vitamins, ionones, and other fragrance compounds.

In flavor formulations, geranial delivers a sharp, fresh citrus note used in beverages, confectionery, and citrus-type flavor blends where high-impact lemon character is required. Fragrance manufacturers use it as a building block for ionones and pseudoionones, which underpin violet and woody fragrance families across fine perfumery and functional products.

In personal care, it contributes to citrus-forward scent profiles in soaps, shampoos, and lotions. The pharmaceutical and nutraceutical industries source it as an intermediate. It is used specifically in the synthesis of Vitamin A and beta-carotene. Geranial is supplied as a pale yellow liquid, typically as part of citral mixtures or in isolated isomer form.

Standard commercial grades include technical and fragrance-grade specifications, with high-purity isolates available for pharmaceutical synthesis applications. Packaging ranges from small drums to bulk quantities suited to industrial fragrance and synthesis operations, ensuring stability and quality for diverse manufacturing needs.
