    Isovaleronitrile (3-Methylbutanenitrile) – CAS 625-28-5

    Isovaleronitrile, also known as 3‑Methylbutanenitrile, is a branched aliphatic nitrile characterized by a terminal cyano group on a short carbon chain. As a defined low‑molecular‑weight organic nitrile, it is handled as a specialty chemical intermediate within regulated industrial and research chemical supply chains. Isovaleronitrile (CAS 625-28-5) is supplied as a discrete molecular substance for professional use in controlled environments, with emphasis on material identification, documentation, and compliance rather than end‑use formulation.
    This material is provided with standardized specifications and complete technical documentation including MSDS, TDS, and COA, supporting compliant handling and traceability.

    Application Areas

    organic synthesis
    Pharmaceutical intermediates: used for synthesizing drug molecules (such as sedatives, antiviral drugs) or amino acid derivatives.
    Pesticide synthesis: used as a precursor to prepare insecticides or herbicides (such as pyrethroids).
    Flavor industry: Isovaleric acid or isoamylamine is produced by hydrolysis or reduction reaction, which is used to prepare fruit flavor or milk flavor essence.
    chemical research
    Solvent or reaction medium: used as a polar non proton solvent in special reactions.
    Catalyst ligand: used in metal organic chemistry (such as palladium catalyzed coupling reactions).

    Storage conditions

    Keep the container sealed, store in a cool, dry place, and ensure good ventilation.
    Avoid contact with oxidants to prevent decomposition.
    Keep away from sources of fire, heat, and static electricity, and prevent direct sunlight

    Safety precautions

    Respiratory protection: When operating in a fume hood, wear an organic vapor proof mask (such as N95 or higher).
    Skin protection: Wear butyl rubber gloves, goggles, and chemical protective clothing.
    Eye protection: Use chemical goggles or face shields.
