Diethyl 1,4-cyclohexanedicarboxylate (also known as Fructalate®, 1,4-Cyclohexanedicarboxylic acid diethyl ester, CAS: 72903-27-6) is a cycloaliphatic diester with the molecular formula C₁₂H₂₀O₄ and a molecular weight of 228.28 g/mol. It appears as a colorless to pale yellow liquid with a pleasant, fruity odor. The compound is a mixture of cis and trans stereoisomers, with the pure trans isomer identified by CAS number 19145-96-1. It is soluble in organic solvents such as ethanol and ether but has limited solubility in water due to its hydrophobic cyclohexane ring structure. Key physical properties include a boiling point of 285–289°C, a density of approximately 1.049 g/cm³ at 20°C, and a refractive index of 1.450–1.454.
As a versatile cycloaliphatic diester, diethyl 1,4-cyclohexanedicarboxylate is valued across multiple industrial sectors. It serves as a key precursor for phthalate-free plasticizer systems (such as DINCH), a monomer or building block in high-performance polymer synthesis, a coalescing agent in waterborne coatings and adhesives, and a specialty fragrance ingredient (Fructalate®) for fine perfumery and personal care products. Market demand is closely linked to the global shift toward phthalate-free plasticizers, the expansion of high-performance coatings and polymer industries, and the growing appetite for unique fruity fragrance notes in specialty perfumery. Based on its chemical characteristics and industrial chain position, this article systematically analyzes international market dynamics of diethyl 1,4-cyclohexanedicarboxylate, focusing on core application scenarios, competitive landscape, regional differences, regulatory trends, and future outlook, providing strategic references for industry participants.
Core Application Fields and Demand
Market demand for diethyl 1,4-cyclohexanedicarboxylate is concentrated in three major sectors: phthalate-free plasticizer precursors and polymer synthesis (≈40-45% of global consumption), fragrances and specialty chemicals (≈30-35%), and coatings, adhesives, and industrial formulations (≈15-20%), with additional demand from pharmaceutical intermediates and agrochemicals (≈5-10%).
In the phthalate-free plasticizer and polymer synthesis sector, this compound serves as a crucial building block for producing non-phthalate plasticizers, which are increasingly preferred due to regulatory pressure on traditional phthalates (e.g., DEHP, DINP) in food-contact, medical, and children‘s products. The rigid cyclohexane ring structure imparts excellent thermal stability, low volatility, and good compatibility with a wide range of polymers, making it ideal for flexible PVC, polyurethanes, and engineering plastics. The compound also acts as a key monomer in the synthesis of novel fluorinated polymers and specialty polyesters, where it contributes to enhanced solubility, thermal stability, and mechanical properties. The cis/trans isomer ratio directly affects polymer crystallinity and performance, with trans-enriched grades (>9:1) ensuring maximum polymer crystallinity and mechanical strength in melt polycondensation with 1,4-cyclohexanedimethanol. Additionally, the compound has been explored as an indirect food additive in food packaging materials.
In the fragrances and specialty chemicals sector, diethyl 1,4-cyclohexanedicarboxylate is marketed under the trade name Fructalate®, where it is valued for its unique fruity, raspberry, apple, and ethereal odor profile. It provides incredible volume to perfume compositions, with remarkable blooming properties, long-lastingness, and fruity lift. The compound demonstrates excellent alkaline stability and substantivity (48 hours) in detergents and cleaners where conventional fruity esters hydrolyze, with a persistent raspberry/apple note at 0.5-10% usage. It is widely used in laundry detergents, fabric softeners, air fresheners, and reed diffusers. The compound carries no IFRA restriction, making it a versatile and safe choice for formulators. Its subtle yet impactful presence enhances the perceived cleanliness and sophistication of everyday products.
In the coatings, adhesives, and industrial formulations sector, the compound functions as an effective coalescing agent in waterborne latex coatings, helping to lower the minimum film formation temperature (MFFT) and improve film formation without compromising hardness or durability. Resins incorporating the 1,4-cyclohexanedicarboxylate structure are also used in stabilized exterior coil coatings, where they provide excellent weatherability and chemical resistance. Additionally, the compound serves as a solvent and softener in industrial applications such as coatings, dyes, rubber, and plastics.
