muguet dienal
Muguet dienal is a medium-strength floral aldehyde with a waxy green watery muguet orchid scent, used primarily in fragrance formulations.
General Material Description
Muguet dienal, chemically identified as (3S,6E)-3,7,11-trimethyl-6,10-dodecadienal, represents a floral aldehyde compound featuring a molecular formula of C15H26O. It presents as a substance with prominent medium-strength floral characteristics noted as waxy, green, watery, and reminiscent of muguet orchid and cyclamen floral notes. Synonyms include biomuguet (Takasago) and laevo-dihydrofarnsal, among others. This aldehyde is naturally occurring in botanical sources such as lemon (Citrus limon) and the orchid species Phalaenopsis japonica. Its sensory signature and physicochemical profile render it significant for fragrance agent applications. The compound is indexed under PubChem CID 44256573, facilitating reliable reference in chemical databases. Its derivation is generally from natural extracts or synthesis tailored for use in perfumery.
Occurrence, Applicability & Potential Uses
Muguet dienal occurs naturally in lemon and Phalaenopsis japonica, contributing to their characteristic aromatic profiles. Its floral aldehyde scent is leveraged primarily in fragrance agents for perfumery and aroma industries. According to IFRA (Global) guidelines, usage levels are established to ensure safe application in consumer products, although this compound is specifically not recommended for flavoring uses. Its long-lasting substantivity and medium floral intensity make it valuable in formulating complex fragrance compositions aimed at mimicking fresh floral bouquets or enhancing floral sweetness in perfumes and personal care products.
Physico-Chemical Properties Summary
Muguet dienal has a molecular weight of approximately 222.37 g/mol and a notable log P value around 5.31 indicating moderate lipophilicity, which influences its solubility and partitioning behavior in formulations. It exhibits a specific gravity between 0.861 and 0.871 at 25 °C, with a refractive index ranging from 1.466 to 1.472 at 20 °C. Optical rotation is reported between −9 and −3, reflecting its stereochemical configuration relevance in odor perception. Water solubility is low, estimated at about 0.35 mg/L at 25 °C, affecting its dispersion in aqueous base products. These properties guide formulators in choosing suitable solvents and concentrations, ensuring compound stability and odor profile preservation within fragrance blends.
