Product Overview
Isopropyl Alcohol 99% Technical Grade is a volatile, colorless solvent that evaporates fast and dissolves a broad range of non-polar compounds on contact. At 99% concentration, this IPA delivers near-anhydrous performance — less than 1% water — making it the go-to solvent when residual moisture interferes with a process. CAS 67-63-0.
Technical Grade means this isopropanol is produced for industrial and general-purpose solvent work where trace-level impurity control is not the primary concern. It is the practical choice for cleaning lines, degreasing parts and flushing equipment — anywhere the job demands a strong, fast-evaporating solvent at a working price point. Buyers who need tighter analytical specifications should evaluate a higher-purity grade for that application.
Alliance Chemical offers this IPA in sizes from 1-quart bottles through 330-gallon totes, covering bench-scale testing through full production volumes.
Why This Concentration
The 99% concentration matters because water is the enemy of many solvent tasks. In parts cleaning, residual water leaves spots and slows drying. In extraction work, water can pull unwanted polar compounds into the solvent phase. A 99% IPA minimizes those problems without the cost of a higher-purity analytical grade.
Compare that to the familiar 70% rubbing-alcohol blend: a 70/30 IPA-water mix is designed for disinfection contact time, not solvent strength. At 99%, nearly all of the liquid is active solvent and the flash point sits at 53 °F — well below ambient — so the material evaporates quickly and cleanly from surfaces. That fast evaporation is an advantage on a production floor, but it also means vapor management and ignition-source control are part of the job.
Technical Grade is the right pick when the process does not demand a certificate of purity against an analytical standard. If your workflow involves wiping down stainless assemblies, dissolving adhesive residue, or preparing surfaces before coating, Technical Grade IPA at 99% does the work at a lower cost per gallon than Technical or Technical alternatives.
Chemical Profile
Isopropyl Alcohol 99% Technical Grade is a colorless liquid with a sharp, characteristic alcohol odor. Its molecular formula is C3H8O (molecular weight 60.10) and it is fully miscible with water — solubility is reported at 100 mg/mL or greater at 72 °F. The liquid is lighter than water at a density of approximately 0.785 at 68 °F (roughly 6.5 lb per gallon). Vapor pressure is notable: 33 mmHg at 68 °F, climbing to 40 mmHg at 74.8 °F, which accounts for its rapid evaporation rate at room temperature. Vapors are heavier than air and will collect in low-lying areas if ventilation is inadequate. The flash point is 53 °F, classifying it as a highly flammable liquid (per the product's GHS classification).
Industrial Applications
IPA 99% Technical Grade serves as a workhorse solvent across several sectors. Below are the most common applications our customers use it for.
-
Surface Cleaning and Degreasing.Dissolves oils, greases and light adhesive residues from metal, glass and plastic surfaces. In manufacturing, it is used to prepare parts before painting, bonding, or coating — anywhere a residue-free surface is required. The fast evaporation at 99% concentration leaves surfaces dry within seconds.
-
Solvent for Extraction.Technical and chemical processing operations use IPA to extract target compounds from raw materials. The near-anhydrous concentration reduces water carry-over during liquid–liquid extraction steps.
-
Cosmetic and Personal-Care Formulation.IPA functions as a solvent vehicle in formulations such as lotions, hair sprays and aftershaves, helping dissolve active ingredients and control viscosity.
-
General Technical Use.Used for rinsing glassware, preparing surfaces and as a reaction solvent in procedures where high analytical purity is not specified.
Handling & Storage
This product carries a GHS signal word ofDanger(per the product's GHS classification). The applicable hazard statements are:
- H225 — Highly flammable liquid and vapor
- H319 — Causes serious eye irritation
- H336 — May cause drowsiness or dizziness
Operators should wear chemical-splash goggles and nitrile or butyl-rubber gloves when handling. In poorly ventilated spaces, use a NIOSH-approved organic-vapor respirator. Vapors are heavier than air and can travel to ignition sources at floor level — eliminate open flames, sparks and hot surfaces in the work area.
Store in a cool, well-ventilated area away from heat, sparks and direct sunlight. Keep containers tightly closed when not in use. HDPE or glass containers are appropriate; verify compatibility with any elastomers or plastics the IPA will contact, as prolonged exposure can soften certain polymers. Keep away from strong oxidizers and concentrated acids to prevent hazardous reactions. Ground and bond containers during transfer to prevent static discharge — with a flash point of 53 °F, ignition risk during pouring is real.
