n-Propyl Alcohol ACS Grade

Product Overview

n-Propyl Alcohol ACS Grade — also known as propan-1-ol — is a high-purity, primary aliphatic alcohol with the molecular formula C3H8O and a molecular weight of 60.10. As a clear, colorless liquid featuring a characteristic sharp, musty odor similar to rubbing alcohol, it serves as a critical solvent in various precision manufacturing and laboratory environments. Alliance Chemical distributes this product to meet the rigorous demands of industrial compounding, where high-grade alcohols are essential for stable chemical reactions and uniform physical properties. This compound features a density of approximately 0.803 at 68 °F (6.5 lb/gal) and is fully miscible in water.

The chemical purity of our n-propyl alcohol ensures reliable performance across diverse industrial processes, including its use in cosmetics, hair preparations, and window cleaners. It is widely employed in the synthesis of specialized chemical intermediates and perfumes, acting as a carrier solvent that evaporates cleanly without leaving unwanted residue. In coatings and specialized dye solutions, it functions as a diluent and coupling agent, improving flow characteristics and polymer solubility. This product is strictly regulated and handled under rigorous quality control standards to guarantee that each batch meets strict physical property criteria prior to shipping.

Why This Grade

Choosing ACS Grade n-propyl alcohol guarantees a level of purity that meets or exceeds the specifications set by the American Chemical Society. This grade is critical for applications that cannot tolerate trace contaminants, such as analytical testing, reagent preparation, and high-precision electronic manufacturing. In these environments, even minor trace metals, moisture, or organic impurities can interfere with sensitive instruments, compromise chemical synthesis, or cause unwanted side reactions. By utilizing this certified grade, facilities protect their equipment and ensure repeatable, reliable outcomes in every single batch.

Using a lesser, non-certified grade of n-propanol can lead to catastrophic failure modes in industrial processes. For instance, in lacquer formulations and dye solutions, high water content or organic impurities can cause phase separation, improper drying times, or haziness in the final coating. In organic synthesis, trace contaminants can poison expensive catalysts or drastically reduce yield, resulting in costly downtime and product waste. To prevent these processing failures and maintain strict operational compliance, selecting ACS Grade is a necessary safeguard for quality-driven industrial operations.

Industrial Applications

• Formulation of lacquer and specialized coatings, where it improves flow, levelling, and drying characteristics without leaving behind residue.
• Carrier solvent for active ingredients in high-end cosmetic formulations, hair preparations, and perfumes to ensure safe, stable suspension.
• High-purity solvent for analytical chemistry laboratories executing organic synthesis, chromatographic separations, and preparation of standard reagent solutions.
• Manufacture of dye solutions and printing inks, ensuring optimal solubility of colorants and consistent evaporation rates on various substrates.
• Intermediate in chemical manufacturing processes for synthesizing propyl esters, propylamines, and other downstream industrial chemical products.

Hazmat & Shipping

n-Propyl Alcohol ACS Grade is classified as a hazardous material for transport. It must be shipped as UN1274, Hazard Class 3, Packing Group II, with the proper shipping name N-PROPANOL. The signal word for this chemical is Danger. Due to its classification as a highly flammable liquid and vapor, all transport, storage, and handling must comply strictly with Department of Transportation regulations. We ship our n-propyl alcohol in compliant packaging to ensure safety during transit to your facility.

When handling this compound, personnel must wear appropriate personal protective equipment (PPE) designed to mitigate the risks associated with its GHS classifications. This includes GHS hazard statements H225 (highly flammable liquid and vapor), H318 (causes serious eye damage), and H336 (may cause drowsiness or dizziness). Required PPE includes chemical-resistant safety goggles, face shields, and protective gloves made of nitrile or butyl rubber. To prevent vapor inhalation, ensure adequate local exhaust ventilation or wear respiratory protection in confined workspaces. GHS pictograms are not applicable based on current canonical definitions.

Handling & Storage

Store n-propyl alcohol in a cool, dry, well-ventilated area away from direct sunlight, heat, sparks, open flames, and other ignition sources. Keep containers tightly closed when not in use, maintaining storage temperatures ideally between 50 °F and 85 °F. This compound is compatible with stainless steel, carbon steel, and high-density polyethylene (HDPE) containers, but can degrade certain plastics and rubbers over prolonged contact. Avoid storage near incompatible substances, including strong oxidizing agents, acids, halogens, and aluminum, as contact may trigger exothermic reactions or container degradation.
