2,4-Dinitrophenol (DNP) Analysis

The 2,4-Dinitrophenol (DNP) Analysis is a targeted laboratory test designed to confirm the identity and determine the amount of 2,4-dinitrophenol in oral dosage forms and raw active pharmaceutical ingredient (API) powders.

The analysis is suitable for pills, tablets, and capsules, with results reported in milligrams per tablet or capsule. Raw API powders can be evaluated by percentage content, with optional purity reporting in % (m/m).

About 2,4-Dinitrophenol (DNP)

2,4-Dinitrophenol (DNP) is a synthetic chemical compound that acts as an uncoupler of oxidative phosphorylation, disrupting normal cellular energy production and increasing heat generation.

DNP has historically been investigated for several industrial and biological applications but is highly toxic and is not approved as a weight-loss drug. Exposure can cause serious and potentially life-threatening adverse effects.

Key Features

Important Notice

• This analysis is specifically intended for 2,4-dinitrophenol (DNP). It does not automatically screen the sample for related compounds, contaminants, or undeclared substances.
• For oral products, the minimum amount of DNP required for evaluation is 20 mg per pill, tablet, or capsule. For raw API powders, the minimum content is 5%. Samples below these values may not be reliably evaluated within the standard scope of the analysis.
• Purity reporting in % (m/m) is available only for raw API powders.
• DNP is a highly toxic compound. Laboratory analysis should not be interpreted as confirmation that a product is safe for human consumption.
