Safety is paramount in any chemical handling environment. Understanding the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) pictograms, signal words, and hazard statements associated with a compound like 3-Bromo-2-methyl-5-nitropyridine (CAS: 186593-42-0) is crucial for safe laboratory practices and informed procurement decisions. As a responsible manufacturer and supplier, we prioritize the clear communication of such safety information.

GHS Classification for 3-Bromo-2-methyl-5-nitropyridine

Based on available data and its chemical structure (C6H5BrN2O2), 3-Bromo-2-methyl-5-nitropyridine typically carries the following GHS classifications:

  • Signal Word: Warning
    The signal word 'Warning' indicates that the substance presents less severe hazards than those designated by the signal word 'Danger.' However, it still warrants careful handling and adherence to safety protocols.
  • GHS Pictograms: GHS07
    The GHS07 pictogram, often depicted as an exclamation mark, signifies several potential hazards, including:
    • Acute toxicity (harmful)
    • Skin irritation
    • Eye irritation
    • Skin sensitization
    • Specific target organ toxicity – single exposure (respiratory tract irritation)

Key Hazard Statements (H-Statements):

These statements provide more specific details about the nature of the hazards:

  • H315: Causes skin irritation. This means direct contact with the skin can lead to redness, inflammation, or discomfort.
  • H319: Causes serious eye irritation. Contact with the eyes can result in significant irritation, pain, and potential temporary vision impairment.
  • H335: May cause respiratory irritation. Inhalation of dust or vapors can irritate the respiratory tract, leading to coughing or shortness of breath.

While not always listed as primary hazards, it's also important to note that brominated and nitro-containing organic compounds can sometimes exhibit other hazards, such as acute toxicity if ingested or inhaled in significant quantities. Always consult the most up-to-date Safety Data Sheet (SDS) provided by the supplier for comprehensive information.

Safe Handling and Procurement Considerations

When purchasing 3-Bromo-2-methyl-5-nitropyridine from a reputable manufacturer or supplier, ensure that a detailed SDS is provided. This document will outline recommended personal protective equipment (PPE) – such as gloves, safety goggles, and lab coats – and appropriate engineering controls (e.g., fume hoods) for handling the material.
