Product Introduction

1,2-Dichlorobenzene (CAS 95-50-1)

1,2-Dichlorobenzene (also known as ortho-dichlorobenzene, o-DCB, ODCB) is a colorless, clear organic liquid with a mild, sweet aromatic odor. Its molecular formula is C₆H₄Cl₂, molar mass 147.00 g/mol, boiling point 180–183°C, melting point -16.7°C, and density ~1.305 g/cm³ (20°C). It is insoluble in water but miscible with most organic solvents (ethanol, benzene, ether). Classified as a hazardous chemical (UN 1591, Class 6.1 toxic; flammability Class 3).

Main Uses

1. High-Boiling SolventDissolves waxes, gums, resins, tars, rubber, oils, and asphalt; used in paint, varnish, and adhesive formulations.

2. Metal & Industrial CleaningEffective degreaser/cleaner for metal surfaces, engine parts (removes carbon/lead deposits), and electronic components; acts as a metal polish ingredient.

3. Chemical IntermediateKey precursor for dyes (vat dyes), agrochemicals (pesticides/fungicides), and pharmaceutical intermediates.

4. Heat Transfer & PlasticsServes as a heat transfer medium (Dowtherm E), epoxy diluent, and polymer wet-spinning solvent (reduces fiber thermal shrinkage).

5. Pesticide & FumigantUsed as an insecticide (termites/locust borers) and fumigant/deodorizer; removes sulfur from illuminating gas.

6. Specialty ApplicationsPreferred solvent for fullerene dissolution in advanced materials research.

Packaging

· Industrial Grade (Bulk): 250 kg net steel drums (UN-approved, sealed); also 25 kg plastic drums or 200 L iron drums.

· Laboratory/Reagent Grade: 100 mL / 500 mL / 2.5 L glass bottles (amber, ground-glass stopper); 25 L/200 L HDPE drums for semi-bulk.

· Specifications: Purity ≥99.0% (industrial) or ≥99.5% (high-grade); moisture ≤0.1% max.

· Labeling: Hazard labels (toxic, flammable), CAS 95-50-1, UN 1591, and safety data.

Summary

1,2-Dichlorobenzene (o-DCB) is a versatile, high-boiling aromatic solvent and chemical intermediate. It serves industrial cleaning, chemical synthesis, heat transfer, and agrochemical sectors, with packaging ranging from 250 kg steel drums (bulk) to glass bottles (lab use).
