Xylene ACS Grade

Product Overview

Xylene ACS Grade is a high-purity solvent mixture of ortho-, meta-, and para-xylene isomers, commonly referred to as Xylol or Dimethylbenzene. As an ACS Reagent Grade chemical, this product meets the strict purity standards required for critical laboratory and industrial applications, validated by gas chromatography (GC). It features a boiling range of 137–144°C and exceptionally low water content, making it an ideal choice for moisture-sensitive formulations.

Alliance Chemical supplies Xylene ACS Grade to industrial buyers requiring consistent evaporation rates and solvency power. Its low acidity (≤0.0003 meq/g) and minimal trace metals prevent catalyst poisoning in chemical synthesis and ensure baseline stability in HPLC mobile phases. This solvent is compatible with High-Density Polyethylene (HDPE) and glass containment. Whether used for thinning high-performance coatings, organic synthesis, or cleaning industrial machinery, this product delivers reliable performance backed by rigorous quality control.

Safety & Handling

Xylene is a flammable liquid (Class 3) and must be handled with appropriate safety precautions. Store in a cool, dry, well-ventilated area away from ignition sources, heat, and direct sunlight. Keep containers tightly closed when not in use to prevent vapor accumulation. Personnel should utilize chemical-resistant gloves, eye protection, and respiratory protection where ventilation is insufficient.

Shipping Information: This product is regulated as Hazardous Material for transport (UN 1307, Xylene, Class 3, PG III). Alliance Chemical ensures all packaging, including 1-gallon bottles and 55-gallon drums, meets DOT and UN compliance standards for safe delivery.
