  • Chemical Profile

Product Overview

n-Heptane 99% ACS is a high-purity, straight-chain alkane solvent (CAS 142-82-5) tailored for critical laboratory and industrial applications. Recognized for its low reactivity and non-polar nature, this ACS-grade solvent serves as a standard in analytical workflows, including gas chromatography (GC) and high-performance liquid chromatography (HPLC). With a typical assay of 99.8% and strictly controlled trace constituents, it ensures minimal baseline noise and interference.

Supplied with a comprehensive Certificate of Analysis (CoA), this product meets the rigorous specifications of the American Chemical Society. It features low water content (<0.02%), minimal UV absorbance, and controlled evaporation residue. It is the preferred choice for engineers and laboratory professionals requiring a consistent, high-specification hydrocarbon solvent for extraction, synthesis, and precision cleaning.

Key Properties

  • Assay: min 99.0% (Typical 99.8%)
  • Grade: ACS (American Chemical Society)
  • CAS Number: 142-82-5
  • Formula: C7H16
  • Water Content (Karl Fischer): max 0.05%, typical 0.02%
  • Color (APHA): max 10
  • Residue after Evaporation: max 10 ppm
  • Sulfur Compounds (as S): max 0.005%

Common Applications

  • Chromatography Solvent: Utilized as a mobile phase in HPLC and a solvent in GC due to its lack of UV absorption at higher wavelengths and low volatility residue.
  • Organic Extraction: Effective non-polar solvent for liquid-liquid extraction of fats, oils, and waxes in biological and botanical processing.
  • Precision Cleaning: Used for degreasing and cleaning precision instruments and optics where residue-free evaporation is critical.
  • Synthesis and Formulation: Acts as an inert reaction medium in organic synthesis and a component in adhesive and coating formulations.
  • Calibration Standard: serves as a reliable reference standard for octane rating determinations and detector calibration.

Safety Precautions

n-Heptane is a flammable liquid and vapor. Store in a cool, well-ventilated area away from ignition sources, heat, and direct sunlight. Keep containers tightly closed when not in use. This product is incompatible with strong oxidizing agents.

Handling: Wear appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves (Nitrile recommended), safety goggles, and protective clothing. Ensure adequate ventilation or use fume hoods during handling to avoid inhalation of vapors.

Transport: Shipping regulated as UN 1206, Heptanes, Class 3, Packing Group II.

Benefits

ACS Grade Purity: Meets strict American Chemical Society specifications for analytical reliability.
Low Residue: Ensures clean evaporation, critical for gravimetric analysis and precision cleaning.
Versatile Packaging: Available in lab-scale bottles (1 Pint/1 Liter) and industrial bulk sizes (5 Gallon/55 Gallon Drums).
Consistency: High batch-to-batch consistency reduces variable factors in sensitive research and manufacturing processes.
