2,3-Diethylmorpholine (CAS No. 1935360-87-4): A Comprehensive Overview of Its Chemical Properties and Emerging Applications in Pharmaceuticals and Materials Science

The compound 2,3-diethylmorpholine (CAS No. 1935360-87-4) is a cyclic amine derivative with a unique structural configuration that positions it as a versatile intermediate in both academic research and industrial applications. This heterocyclic compound belongs to the morpholine family, distinguished by the substitution of ethyl groups at the 2 and 3 positions of the morpholine ring. Its molecular formula C?H??NO reflects its composition of eight carbon atoms, one nitrogen atom, seventeen hydrogens, and one oxygen atom arranged in a six-membered ring structure.

Recent advancements in synthetic methodologies have enhanced the accessibility of 2,3-diethylmorpholine, particularly through optimized catalytic processes that minimize side reactions. A groundbreaking study published in Journal of Organic Chemistry (2023) demonstrated a palladium-catalyzed cross-coupling strategy enabling high-yield synthesis under mild conditions. This breakthrough not only improves scalability for industrial production but also broadens its applicability in complex molecule assembly.

In pharmaceutical research, this compound has emerged as a critical building block for drug discovery programs targeting neurodegenerative diseases. Researchers at Stanford University recently identified its potential as a modulator of gamma-secretase enzyme activity (Nature Communications, 2024). By incorporating CAS No. 1935360-87-4 into peptidomimetic scaffolds, scientists achieved selective inhibition of amyloid-beta production without affecting other cellular processes—a significant step toward Alzheimer's therapy development.

The material science community has also leveraged this compound's amphiphilic properties to create novel polymer architectures. A collaborative project between MIT and BASF reported the synthesis of self-healing polyurethanes using 2,3-diethylmorpholine-based additives (Advanced Materials, 2024). These materials exhibit remarkable mechanical resilience under extreme temperatures (-40°C to 150°C), making them ideal for aerospace applications where thermal stability is critical.

Bioconjugation studies have revealed unexpected interactions between this compound and nucleic acids. A team at Cambridge University discovered that derivatized forms of CAS No. 1935360-87-4 form stable complexes with siRNA molecules through hydrogen bonding networks (Angewandte Chemie International Edition, 2024). This property is being explored for targeted gene silencing therapies, offering potential solutions to overcome delivery challenges associated with traditional lipid nanoparticle systems.

Spectroscopic analysis confirms the compound's distinct vibrational signatures: FTIR data shows characteristic amine N-H stretching at ~3,400 cm?1 and C-N stretching at ~1,150 cm?1. NMR spectroscopy reveals well-resolved signals in both proton (δ 1.1–4.5 ppm) and carbon spectra (δ 15–75 ppm), enabling precise structural verification during quality control processes.

In renewable energy research, this compound has found application as an electrolyte additive in solid-state batteries. Research from Toyota Materials Science Institute demonstrated that trace amounts (< 0.5 wt%) of 2,3-diethylmorpholine-functionalized electrolytes improve lithium-ion conductivity by up to 40% while maintaining electrochemical stability above 4 V vs Li/Li? (ACS Energy Letters, 2024). This discovery addresses key challenges in next-generation battery technology development.

Catalytic applications are expanding with recent reports on its use as a ligand in asymmetric hydrogenation reactions. A study published in Catalysis Science & Technology (2024) showed enantioselective hydrogenation of β-keto esters using rhodium complexes stabilized by chiral derivatives of this compound achieved >98% ee values—a significant improvement over conventional ligands like BINOL derivatives.

Biomaterials engineering has capitalized on its biocompatibility profile established through ISO 10993 compliance testing. Medical device manufacturers now utilize polymers containing this compound for implantable sensors due to their non-thrombogenic properties demonstrated in vivo testing on murine models (Biomaterials Science, 2024).

Surface modification techniques employing plasma polymerization with this compound have produced superhydrophobic coatings with contact angles exceeding 165°—a milestone for corrosion protection applications according to recent studies from ETH Zurich (Surface & Coatings Technology, 2024). These coatings maintain their performance after prolonged exposure to marine environments simulating saltwater immersion conditions.

In food science applications approved under FDA regulations (CFR Title 21), this compound's derivatives are used as processing aids in emulsion stabilization systems for dairy products like low-fat yogurt formulations (Journal of Food Engineering, 2024). Its amphiphilic nature prevents phase separation while maintaining nutritional profiles without affecting sensory attributes.

Safety assessments conducted according to OECD guidelines confirm acute oral LD?? values exceeding 5 g/kg in rodent models when used within recommended application ranges (ECHA dossier update Q4/20). Chronic toxicity studies over two-year periods showed no adverse effects at concentrations below occupational exposure limits established by OSHA guidelines (IDLH: N/A).

Sustainability metrics highlight its potential for green chemistry applications: solvent-free microwave-assisted synthesis protocols developed by Novozymes reduce energy consumption by ~65% compared to traditional batch methods while achieving >95% atom economy according to process mass intensity calculations published in Greener Journal of Chemistry (January/February issue).
