    Description


    Description:
    2-Aminopyrimidine (CAS 109-12-6) is a heterocyclic organic compound with the molecular formula ​C₄H₅N₃ and a molecular weight of ​95.10 g/mol. It is a pyrimidine derivative characterized by a six-membered aromatic ring containing two nitrogen atoms at positions 1 and 3, with an amino group (-NH₂) substituted at position 2. The compound exists as a white to off-white crystalline solid at room temperature, with a melting point of ​85–88°C and a boiling point of ​267°C. It is sparingly soluble in water but dissolves readily in polar organic solvents such as ethanol, methanol, and dimethyl sulfoxide (DMSO).


    As a versatile building block in organic synthesis, 2-aminopyrimidine is widely utilized in pharmaceutical, agrochemical, and material science industries. Its structural similarity to nucleic acid bases (e.g., cytosine and thymine) makes it a critical scaffold for designing bioactive molecules. The compound is commercially available in high purity grades (>98%) and is typically supplied in sealed containers under inert gas to prevent degradation.

    ​2. Applications and Use Cases
    ​2.1 Pharmaceutical Industry
    2-Aminopyrimidine is a key intermediate in synthesizing ​kinase inhibitors, ​antiviral agents, and ​anticancer drugs. For example:
    Imatinib, a tyrosine kinase inhibitor for chronic myeloid leukemia, incorporates a pyrimidine backbone derived from 2-aminopyrimidine.
    Baricitinib, a JAK inhibitor for rheumatoid arthritis, utilizes 2-aminopyrimidine as a core structure.
    Antimicrobial agents such as ​trimethoprim rely on pyrimidine derivatives to inhibit bacterial dihydrofolate reductase.
    ​2.2 Agrochemicals
    The compound is used to develop herbicides and fungicides. Its ability to disrupt enzymatic pathways in plants and pests makes it valuable for crop protection.
    ​2.3 Material Science
    In coordination chemistry, 2-aminopyrimidine acts as a ligand for metal complexes, enabling applications in catalysis and luminescent materials.

    ​3. Biological Mechanisms
    ​3.1 Role in Kinase Inhibition
    2-Aminopyrimidine derivatives are renowned for their ability to inhibit ​protein kinases, enzymes critical for signal transduction in cellular processes. The amino group at position 2 enhances hydrogen bonding with kinase ATP-binding pockets, enabling competitive inhibition. For instance:
    EGFR (Epidermal Growth Factor Receptor) inhibitors like gefitinib utilize pyrimidine scaffolds to block aberrant signaling in cancer cells.
    ​CDK (Cyclin-Dependent Kinase) inhibitors arrest the cell cycle by binding to CDK-ATP sites.
    ​3.2 Antifolate Activity
    In antimicrobial and anticancer contexts, 2-aminopyrimidine derivatives interfere with ​dihydrofolate reductase (DHFR), an enzyme essential for nucleotide synthesis. By mimicking dihydrofolate, these compounds deplete tetrahydrofolate pools, halting DNA replication in pathogens or rapidly dividing cancer cells.
    ​3.3 Antiviral Action
    Pyrimidine analogs, including 2-aminopyrimidine derivatives, inhibit viral polymerases or integrases. For example, HIV reverse transcriptase inhibitors incorporate modified pyrimidines to terminate viral DNA elongation.

    ​4. Usage Guidelines
    ​4.1 Handling and Storage
    Storage: Store in a cool (<25°C), dry place under inert gas (argon or nitrogen) to prevent oxidation. Protect from light and moisture.
    Handling: Use personal protective equipment (PPE), including gloves, lab coats, and safety goggles. Avoid inhalation or skin contact.
    ​4.2 Solubility and Formulation
    For biological assays, dissolve 2-aminopyrimidine in DMSO (up to 50 mg/mL) and dilute in aqueous buffers. Note that prolonged storage in DMSO may degrade the compound.
    In synthetic chemistry, reactions often employ anhydrous solvents (e.g., THF, dichloromethane) under nitrogen atmosphere to enhance stability.
    ​4.3 Safety Data
    GHS Hazard Statements: H302 (Harmful if swallowed), H315 (Causes skin irritation), H319 (Causes serious eye irritation).
    ​First Aid: Rinse skin/eyes with water for 15 minutes if exposed. Seek medical attention for ingestion or inhalation.

    ​5. Synthetic Routes
    2-Aminopyrimidine is synthesized via:
    Condensation Reactions: Heating malononitrile with guanidine derivatives in acidic or basic conditions.
    ​Modified Pinner Synthesis: Reacting amidines with β-ketoesters or β-diketones.
    Catalytic Amination: Transition metal-catalyzed amination of halopyrimidines using ammonia or amines.
    6. Research and Development Trends
    Recent studies focus on:
    PROTACs (Proteolysis-Targeting Chimeras): Incorporating 2-aminopyrimidine to degrade disease-causing proteins.
    Covalent Inhibitors: Designing pyrimidine-based electrophiles (e.g., acrylamides) for irreversible kinase binding.
    AI-Driven Drug Discovery: Screening 2-aminopyrimidine libraries via machine learning to optimize pharmacokinetic properties.

    ​7. Regulatory and Environmental Considerations
    ​REACH Compliance: 2-Aminopyrimidine is registered under EU REACH for industrial use.
    ​Ecotoxicity: Limited data suggest moderate toxicity to aquatic organisms (EC₅₀ ~10 mg/L for algae). Proper waste disposal via incineration is recommended.

    ​8. Conclusion
    2-Aminopyrimidine is a cornerstone of modern medicinal chemistry, offering unparalleled versatility in drug design and industrial applications. Its unique pharmacophoric features and tunable reactivity ensure its continued prominence in scientific and commercial endeavors. Researchers and manufacturers must adhere to safety protocols while leveraging its potential to address unmet medical and technological challenges.
