Isopropyl Alcohol 99% - Technical Grade

Product Overview

Isopropyl Alcohol 99% — Technical Grade, represented by the chemical formula C3H8O and a molecular weight of 60.10, is a highly volatile, colorless liquid utilized across multiple sectors. As an essential chemical intermediate and solvent distributed by Alliance Chemical, this technical-grade fluid serves as a foundational component in industrial processing and formulation workflows. Featuring a characteristic sharp, musty odor, it is highly miscible in water and organic solvents, facilitating diverse chemical reactions and blending operations. Our product is designed specifically to meet the rigorous demands of manufacturing facilities requiring a high-purity, low-moisture solvent without the added cost of analytical-grade reagents.

We supply this technical-grade propan-2-ol to support heavy-duty cleaning operations, solvent extraction, and chemical synthesis. Because technical-grade isopropyl alcohol features minimal water content (typically less than 1%), it functions as an excellent dehydrating agent and carrier solvent. Industries rely on this standard variant to prepare lacquer formulations, dye solutions, and specialized surface coatings. Alliance Chemical ensures that every batch maintains consistent physical properties, supporting predictable batch processing in your facility. We offer a variety of packaging sizes, from single quarts to bulk quantities, ensuring that your specific process demands are met efficiently.

Why This Grade

Selecting the correct grade of isopropyl alcohol is critical for process control and product integrity. Technical Grade 99% represents a high-concentration, industrial-strength solvent designed for applications where minor trace impurities do not interfere with the chemical process. Unlike lower-concentration options, such as 70% aqueous solutions which contain significant water content, the 99% concentration provides the necessary chemical strength for non-aqueous formulations, precise solvent extraction, and quick-drying coatings. By utilizing a 99% anhydrous-equivalent solvent, operators can prevent unwanted water-induced reactions, control viscosity, and maintain proper drying times in paint and coating applications.

Choosing an incorrect grade or a lower concentration can lead to severe process failures and mechanical issues. For instance, introducing a 70% concentration into water-sensitive polyurethane or epoxy formulations can cause premature curing, haziness, or structural weakness due to moisture contamination. In electronics manufacturing or precise equipment cleaning, excess water from lower-grade alcohols leaves behind residue, causes corrosion, or delays evaporation, which can ruin sensitive electrical components. Using anything less than the specified 99% technical grade can compromise the adhesive strength of industrial binders and alter the solubility of critical chemical intermediates. Selecting this high-concentration material ensures that your processes operate within strict, reliable parameters.

Industrial Applications

• Formulation of industrial coatings, lacquers, and varnishes where high-purity solvent evaporation is required for proper film formation.
• As an extraction solvent in the processing of natural oils, resins, and gums within chemical processing facilities.
• Precision cleaning of electronic assemblies, circuit boards, and metallic surfaces where water-sensitive components must remain residue-free.
• An essential raw material in the synthesis of chemical intermediates, including isopropyl esters and various industrial solvent formulations.
• An ingredient in automotive antifreeze mixtures and window cleaner concentrates to lower the freezing point and improve solvency.

Hazmat & Shipping

Isopropyl Alcohol 99% — Technical Grade is classified as a hazardous material for transportation and storage. It is regulated under United States DOT and international transport guidelines as UN1219, Hazard Class 3, Packing Group II, with the proper shipping name Isopropanol. The GHS Signal Word is DANGER, reflecting its highly flammable nature and associated physical hazards. Due to its classification, this material must be shipped and stored in accordance with stringent regulatory frameworks. Alliance Chemical coordinates with certified hazmat carriers to ensure safe transport from our facility to your receiving dock, adhering to all safety requirements.

Handling this chemical requires appropriate personal protective equipment (PPE) keyed directly to its GHS classification codes, including H225, H319, and H336. To mitigate the risk of eye irritation (H319) and skin contact, operators must wear chemical splash goggles, neoprene or nitrile gloves, and protective clothing. Because the vapors can cause drowsiness or dizziness (H336) and are highly flammable (H225), processes should be conducted in well-ventilated areas or under local exhaust ventilation. In confined spaces, NIOSH-approved organic vapor respirators are necessary to ensure exposure limits are not exceeded. Grounding and bonding of all transfer equipment is mandatory to prevent static discharge.

Handling & Storage

Proper handling and storage of technical-grade isopropyl alcohol are essential to maintain product quality and facility safety. Store this volatile liquid in a cool, dry, well-ventilated area, ideally at temperatures between 50°F and 85°F, away from direct sunlight, open flames, or ignition sources. This product is highly compatible with high-density polyethylene (HDPE), stainless steel, and carbon steel containers, but it can degrade certain natural rubbers and plastics over time. Keep containers tightly closed when not in use. Isopropyl alcohol is highly incompatible with strong oxidizing agents, halogens, active metals, and strong acids, which can trigger hazardous exothermic reactions.
