What Is 1,4-Diisopropylnaphthalene?

1,4-Diisopropylnaphthalene (CAS 4132-71-2, molecular formula C₁₆H₂₀, MW 212.33 g/mol) is a dialkyl-substituted polycyclic aromatic hydrocarbon. Its structure consists of a naphthalene bicyclic ring system with isopropyl groups attached at the 1- and 4-positions, rendering the molecule more lipophilic and raising its boiling point compared to unsubstituted naphthalene.

This compound is available from Aladdin Scientific under SKU D769276, supplied for research and specialty chemical applications. As with all aromatic hydrocarbons, it should be handled with appropriate personal protective equipment and stored away from ignition sources.

Key Physicochemical Properties

1,4-Diisopropylnaphthalene is typically a colorless to pale yellow liquid at room temperature. The two isopropyl substituents significantly increase the molecular weight (212.33 g/mol) relative to naphthalene (128.17 g/mol), resulting in a higher boiling point and lower vapor pressure. The compound is hydrophobic and miscible with common organic solvents such as ethanol, acetone, and diethyl ether, while being essentially immiscible with water.

Note: Specific boiling point, density, refractive index, and flash point values should be confirmed against the current certificate of analysis (CoA) provided with each lot. Contact Aladdin Scientific technical support or refer to the product page for the most up-to-date specification data.

Research Applications and Uses

1,4-Diisopropylnaphthalene serves multiple roles in laboratory and industrial research settings:

• High-boiling solvent: Its elevated boiling point makes it suitable for reactions requiring temperatures above those accessible with common solvents.
• Chemical intermediate: Diisopropylnaphthalene isomers are used as precursors or intermediates in the synthesis of more complex aromatic compounds.
• Carrier and process fluid: Diisopropylnaphthalenes have been reported in literature as components in carbonless copy paper systems and specialty fluid formulations, though specific application details should be verified in primary literature.
• Reference standard: High-purity aromatic hydrocarbons are used as reference compounds in analytical chemistry and physicochemical studies.

Researchers are encouraged to consult primary literature for application-specific protocols and to verify suitability of the reagent grade for their intended use.

Safety, Storage, and Handling

As an aromatic hydrocarbon, 1,4-Diisopropylnaphthalene should be handled with standard laboratory precautions:

• Wear appropriate PPE including chemical-resistant gloves, safety goggles, and a lab coat.
• Work in a well-ventilated area or fume hood to minimize inhalation exposure.
• Keep away from heat, sparks, and open flames, as the compound is combustible.
• Store in a tightly sealed container in a cool, dry, well-ventilated location, away from incompatible materials such as strong oxidizers.
• Consult the Safety Data Sheet (SDS) provided by Aladdin Scientific for complete hazard, first-aid, disposal, and regulatory information before use.

Disclaimer: The SDS and CoA accompanying each shipment are the authoritative sources for safety and specification data. Always review these documents prior to handling.
