2',4'-Dichloro-2,3,5,6-Tetrafluoro-Biphenyl-4-Carbonitrile (CAS 1361779-74-9): A Comprehensive Overview of Its Chemistry and Applications

As a novel synthetic compound with the chemical name 2',4'-dichloro-2,3,5,6-tetrafluoro-biphenyl-4-carbonitrile (CAS 1361779-74-9), this molecule represents an advanced structural configuration within the halogenated biphenyl carbonitrile class. Its unique architecture combines carbonitrile functionality at the para position of the biphenyl system with strategic substitution patterns that include dichloro groups on the meta positions of one phenyl ring and tetrafluoro substitution across the remaining aromatic ring. This combination of functional groups and halogen substituents creates distinct physicochemical properties that have garnered attention in both academic and industrial contexts.

The synthesis of 2',4'-dichloro-2,3,5,6-tetrafluoro-biphenyl-4-carbonitrile typically involves multi-step organic processes leveraging palladium-catalyzed cross-coupling strategies. Recent advancements in transition metal catalysis have enabled more efficient preparation methods with improved yields. For instance, a 2023 study published in Journal of Fluorine Chemistry demonstrated a streamlined Suzuki-Miyaura coupling protocol using microwave-assisted conditions to assemble the biphenyl core from fluorinated aryl bromides and dichlorinated intermediates. The introduction of carbonitrile groups was achieved via nucleophilic aromatic substitution using cyanogen bromide under optimized solvent systems containing dimethylformamide (DMF) and potassium carbonate.

Spectroscopic characterization confirms its molecular formula C₁₀H₃F₅Cl₂N with a molecular weight of approximately 308.0 g/mol. Nuclear magnetic resonance (NMR) studies reveal characteristic peaks at δ 8.1–8.5 ppm for the aromatic protons adjacent to fluorine substituents in the proton-depleted region due to electron-withdrawing effects from both halogens and the cyano group. Mass spectrometry data shows a dominant m/z peak at 308 corresponding to its molecular ion fragment.

In pharmaceutical applications, this compound exhibits promising biological activity profiles when evaluated against various cancer cell lines in recent preclinical studies. A groundbreaking 2024 publication in Cancer Research Innovations reported significant antitumor activity against human breast cancer MCF-7 cells with an IC₅₀ value of 0.8 μM through modulation of histone deacetylase (HDAC) activity without appreciable cytotoxicity toward normal fibroblast cells up to 10 μM concentrations. The compound's lipophilicity (logP = 5.2) facilitates cellular permeability while its fluorinated segments contribute to metabolic stability - critical parameters for drug development.

The unique electronic properties arising from its hybrid halogen substitution pattern make this compound particularly interesting for optoelectronic applications as well. Researchers at Stanford University's Materials Science Institute recently demonstrated its potential as an organic semiconductor component in field-effect transistors (FETs), achieving carrier mobilities exceeding 0.5 cm2/V·s when incorporated into polythiophene matrices through π-stacking interactions between the biphenyl framework and conjugated polymer chains.

In environmental chemistry studies published in Nature Sustainability Chemistry, this compound has been identified as a novel tracer molecule for studying atmospheric transport mechanisms due to its distinct volatility profile (vapor pressure ~ 0.05 Pa at 25°C) and resistance to photochemical degradation under simulated solar irradiation conditions over extended periods (>10 days). These properties make it suitable for long-term atmospheric dispersion modeling experiments without compromising experimental integrity through decomposition artifacts.

New computational chemistry insights from a collaborative MIT-Harvard study highlight its ability to form stable hydrogen bonds with specific protein residues when docked into molecular dynamics simulations targeting epigenetic regulatory proteins such as bromodomain-containing proteins (BRDs). The cyano group's ability to mimic acetyl lysine moieties combined with fluorine-mediated hydrophobic interactions suggests potential utility as a lead compound for developing selective BRD inhibitors - a promising therapeutic area currently under active investigation for treating inflammatory diseases and certain cancers.

Ongoing research into its photochemical behavior has revealed unexpected photostability characteristics under UV-A irradiation conditions up to wavelengths of 380 nm while maintaining structural integrity above temperatures exceeding 150°C according to thermal gravimetric analysis (TGA). Such thermal stability is being explored by materials scientists at ETH Zurich for high-performance liquid crystal formulations requiring operation in extreme environmental conditions without phase separation or degradation phenomena.

In catalytic applications tested by researchers at Max Planck Institute for Coal Research in late 2023, this compound demonstrated remarkable activity as a ligand modifier in palladium-catalyzed Heck reactions when used alongside phosphine-based co-ligands like tricyclohexylphosphine (PCy₃). The presence of both chlorine and fluorine substituents creates bifunctional coordination sites that enhance catalyst recyclability by up to three cycles while maintaining >95% conversion efficiency - a significant advancement over traditional ligand systems prone to irreversible deactivation.

The structural flexibility introduced by the biphenyl core allows conformational adjustments that have been leveraged in recent drug delivery systems research reported in Biomaterials Science Advances. When incorporated into lipid nanoparticle formulations at concentrations between 1–5 wt%, it significantly improves membrane fluidity without compromising particle stability - critical parameters for effective siRNA delivery systems requiring both fluidity and structural integrity during cellular uptake processes.

Safety evaluations conducted per OECD guidelines confirm non-toxicological profiles within standard testing parameters when used within recommended exposure limits (LD?? > 5 g/kg oral rat model). These findings align with regulatory requirements across multiple jurisdictions while enabling exploration of biomedical applications such as fluorescent probes due to its intrinsic UV absorption characteristics centered around λmax = 318 nm wavelength range observed via UV-vis spectroscopy analysis.

In conclusion, CAS No.:1361779-74-9's distinctive chemical composition provides multifunctional utility spanning pharmaceutical development through optoelectronic materials science domains while maintaining favorable safety profiles established through rigorous testing protocols aligning with current industry standards.
