2,4-Dinitrophenyl Hydrazine DNP – 100 gram packs

2,4-Dinitrophenylhydrazine (DNPH), also known as 2,4-DNP, is an aromatic hydrazine derivative containing two nitro groups attached to a phenyl ring. With the molecular formula C6H6N4O4, this chemical is widely recognized as a reagent in organic and analytical chemistry, particularly for the identification of carbonyl compounds. It reacts with aldehydes and ketones to form corresponding hydrazone derivatives, which can provide useful evidence for compound identification in qualitative organic analysis. Its distinctive chemical reactivity makes it relevant to supervised chemistry practicals, undergraduate laboratory experiments, and research investigations involving organic functional groups. The 100 g laboratory pack is intended for appropriate scientific applications, subject to the supplied product’s verified specifications and handling requirements. DNPH can present a serious explosion hazard when dry, so its moisture condition must be confirmed and controlled in accordance with the applicable safety documentation.

Frequently Asked Questions About 2,4-Dinitrophenylhydrazine

What is 2,4-Dinitrophenylhydrazine used for in laboratories?

2,4-Dinitrophenylhydrazine is primarily used in qualitative organic chemistry to detect aldehydes and ketones through hydrazone formation. The resulting derivatives can support compound identification and characterization. Its use requires suitable laboratory controls because the reagent presents significant hazards, particularly if allowed to become dry.

What is the molecular formula and molecular weight of 2,4-Dinitrophenylhydrazine?

The molecular formula is C6H6N4O4, and its molecular weight is approximately 198.14 g/mol. Its empirical formula is also C6H6N4O4 because the subscripts cannot be reduced to a simpler whole-number ratio. These values refer to the parent compound, excluding any added water or other formulation components.

What is the CAS number of 2,4-Dinitrophenylhydrazine?

The CAS Registry Number for 2,4-Dinitrophenylhydrazine is 119-26-6. This identifier refers to the parent chemical substance. When ordering a laboratory reagent, purchasers should also verify whether the supplied material is wetted with water or contains other formulation components, as these affect the composition of the product.

Why is the moisture condition important when purchasing 2,4-Dinitrophenylhydrazine?

Dry 2,4-Dinitrophenylhydrazine can be dangerously explosive and sensitive to shock or friction. Commercial preparations are commonly supplied wetted with water to reduce this risk. The moisture condition must be confirmed before purchase and use. Do not allow the material to dry, and do not handle or process material of uncertain moisture condition.

How should 2,4-Dinitrophenylhydrazine be stored and handled safely?

Follow the product-specific Safety Data Sheet and institutional chemical safety procedures. Keep the reagent in its approved, compatible, tightly closed container under the specified storage conditions, and maintain its required wetted condition. Avoid friction, impact, heat, ignition sources, and incompatible chemicals. Handling should be restricted to trained personnel using appropriate protective equipment and suitable facilities.

Storage Conditions for 2,4-Dinitrophenylhydrazine

Store 2,4-Dinitrophenylhydrazine in its original, compatible, securely closed container under the temperature and environmental conditions specified in the applicable Safety Data Sheet. Maintain the approved wetted condition where required and never allow the material to dry. Protect it from heat, ignition sources, impact, friction, and incompatible substances. Storage arrangements must comply with institutional procedures for hazardous reactive chemicals.

Precautions for Handling 2,4-Dinitrophenylhydrazine

Review the current Safety Data Sheet before handling and restrict use to trained personnel in an appropriately equipped laboratory. Wear suitable protective gloves, laboratory clothing, and eye protection, and use appropriate ventilation. Avoid inhalation, skin or eye contact, friction, impact, and heat. Never allow the reagent to dry or attempt to recover dry material through routine handling. Follow approved spill response and hazardous waste procedures, and ensure suitable supervision for educational laboratory activities.
