Chlorobenzene AR 2.5L
Discover the importance of this chemical grade in laboratory analysis and its applications for accurate results.
Chlorobenzene (CHCl) is an aromatic organic compound used in educational and research laboratories primarily as an NMR/IR reference standard, a high-boiling solvent, and a reagent for organic synthesis.
Chlorobenzene AR 2.5L
[Application]: Roles in the Laboratory
IR & NMR Calibration/Fingerprinting: The characteristic Infrared spectrum of chlorobenzene is frequently used in spectroscopy labs as a reference or "fingerprint" to identify aromatic bond vibrations (C-H aromatic stretches >3000 cm¹, C=C ring stretches ~1400--1600 cm¹, and C-Cl stretches). It is also used as an NMR reference or standard.
Reaction Medium (Solvent): Due to its high boiling point (131.7°C), chemical stability, and polarity, it is utilised as an inert solvent for elevated-temperature reactions, interfacial polymerisation, and crystallisation.
Synthesis Precursor: Labs use it as a starting material to demonstrate electrophilic aromatic substitution reactions (such as nitration or halogenation) or to synthesise aniline derivatives and dyes

Safety Guardrails & Hazards
Toxicity: It is toxic and can irritate the skin, eyes, and respiratory system. Prolonged or high-level exposure can cause damage to the liver, kidneys, and central nervous system.
Flammability: It is a flammable liquid. Keep it away from open flames, sparks, and high heat sources (flash point is 27°C / 80.6°F).
Handling: Always handle within a chemical fume hood using proper PPE (nitrile gloves, safety googles). Do not pour down the drain; collect in designated halogenated waste containers.
