MG Chemicals 824, 99.9% Isopropyl Alcohol, ACS Reagent Grade, 1 Gallon / 5 Gallon

MG Chemicals 824 — 99.9% Isopropyl Alcohol, ACS Reagent Grade

MG Chemicals 824 is ultra-pure 99.9% isopropyl alcohol (IPA) at ACS reagent grade — the highest purity standard for laboratory and electronics use. Available in 1-gallon (case of 4) and 5-gallon sizes, it delivers fast-evaporating, zero-residue cleaning of ionic, polar, and non-polar contaminants from PCBs, optical surfaces, precision instruments, and production equipment. Anhydrous and hygroscopic, it also scavenges moisture from surfaces effectively. NSF-listed as acceptable for use in food processing areas where electronics require cleaning without aqueous solutions.

Note: 1 Gallon size (824-1G) is sold as a case of 4 gallons. 5 Gallon (824-20L) is sold as a case of 1.

Frequently Asked Questions

What does "mg chemicals 824 1g" mean?
The SKU 824-1G refers to MG Chemicals' 99.9% ACS reagent grade isopropyl alcohol in the 1-gallon size. Note that this is sold as a case of 4 individual gallons, not a single container.

What is ACS reagent grade IPA and why does it matter?
ACS reagent grade means the IPA meets the American Chemical Society's standards for analytical reagents — ensuring 99.9% minimum purity with controlled levels of water, non-volatile residue, and other impurities. This matters for electronics cleaning because lower-purity IPA can leave trace residues that cause reliability issues.

Is MG Chemicals 824 safe on PCBs and electronic components?
Yes — 824 is a standard choice for PCB cleaning. It leaves no residue, evaporates quickly, and is safe on most plastics and elastomers. It removes flux residues, solder paste, oxides, and ionic contamination effectively.

What is the VOC dilution requirement for California users?
Residential or institutional users in California and several other states (IL, IN, MI, OH, CT, DE, ME, MD, MA, NH, NJ, NY, PA, RI, VT, VA, DC, UT) with 75% VOC limits on electronics cleaners must dilute the product 25% with water or acetone before use. Industrial users are typically exempt.

How does 824 compare to 70% IPA for electronics cleaning?
99.9% IPA (824) is preferred for electronics cleaning because it evaporates faster and leaves no water residue — critical for moisture-sensitive components. 70% IPA contains 30% water, which can cause corrosion or damage if trapped under components. Use 99.9% for PCBs; 70% is better suited for general surface disinfection.
