Product Introduction: 2,4-Dinitrophenol (CAS #: 2004-14-0)

2,4-Dinitrophenol (DNP), identified by CAS number 2004-14-0, is an organic compound with the chemical formula C₆H₄N₂O₅. A yellow crystalline solid with a distinct aromatic odor, DNP is known for its unique chemical properties, which have led to specialized applications in industrial and research settings, though its use is tightly regulated due to safety considerations.

Chemical & Physical Properties

2,4-Dinitrophenol exhibits the following key characteristics:

Appearance: Bright yellow crystals or powder, often with a slight moisture sensitivity.

Melting Point: Approximately 112–114°C, with decomposition occurring at higher temperatures.

Solubility: Moderately soluble in organic solvents (e.g., ethanol, acetone) and sparingly soluble in water.

Chemical Reactivity: It is a strong oxidizing agent and can react vigorously with combustible materials, strong bases, and reducing agents, requiring careful handling

Key Applications

Despite its hazards, 2,4-Dinitrophenol (CAS 2004-14-0) has historical and niche uses in controlled environments:

Industrial Synthesis: It serves as an intermediate in the production of dyes, pharmaceuticals, and pesticides, where its aromatic structure and nitro groups enable specific chemical reactions.

Laboratory Research: In biochemical studies, DNP has been used to investigate mitochondrial function, as it uncouples oxidative phosphorylation, disrupting ATP production in cells.

Historical Uses: It was once utilized in manufacturing explosives and as a wood preservative, though these applications have diminished due to safety concerns and regulatory restrictions

Safety & Handling

2,4-Dinitrophenol is highly toxic and poses severe health risks, requiring strict safety protocols:

Toxicity: Inhalation, ingestion, or skin contact can cause acute poisoning, leading to symptoms such as fever, rapid breathing, organ failure, and even death. It is classified as a potent metabolic uncoupler.

Fire Hazard: It is combustible and may ignite spontaneously when in contact with organic materials; keep away from heat, sparks, and open flames.

Protection: Use impermeable gloves, splash-proof goggles, and a full-face respirator when handling. Work in a well-ventilated fume hood.

Storage: Store in a tightly sealed, labeled container in a cool, dry, and locked area, separate from incompatible substances (e.g., reducing agents, bases).

Note: Due to its high toxicity, 2,4-DNP is subject to strict regulatory controls in most regions. Refer to local laws and the product’s Safety Data Sheet (SDS) for comprehensive guidelines.
