Buy Isopropyl Alcohol (IPA) 99.9% CAS 67-63-0 — Anhydrous Lab & Industrial Grade
Isopropyl Alcohol (IPA) at 99.9% anhydrous purity is one 
of the most widely used and versatile solvents in global 
industrial manufacturing, pharmaceutical production, 
laboratory science, and electronics fabrication. It is 
the workhorse solvent of the modern electronics industry 
and an indispensable process chemical across pharmaceutical, 
cosmetic, and precision cleaning applications worldwide.

While lower-concentration IPA (70%) is widely used as a 
surface disinfectant, anhydrous 99.9% IPA delivers an 
entirely different performance profile — it is a 
water-free precision industrial solvent that leaves 
no aqueous residue, evaporates rapidly without streaking, 
and provides the moisture-free conditions required for 
sensitive electronics, pharmaceutical synthesis, and 
analytical laboratory work. The difference between 70% 
and 99.9% IPA is not a matter of degree — it is a 
fundamentally different product for fundamentally 
different applications.

Why 99.9% Purity Matters

The purity specification of IPA is not merely a quality 
indicator — it is an application-critical parameter that 
determines whether the solvent is suitable for its 
intended use:

99.9% Anhydrous IPA (our product):
- Water content <0.1% — safe for moisture-sensitive 
  electronics and semiconductor processes
- Leaves no aqueous residue on evaporation
- Suitable for lithium-ion battery component cleaning
- Required for pharmaceutical synthesis where 
  anhydrous conditions are specified
- Suitable for optical component cleaning where 
  water spots must be avoided
- Appropriate for analytical laboratory use where 
  water interference must be eliminated

70% IPA (not our product):
- 30% water content — leaves aqueous residue
- Suitable for surface disinfection only
- Not suitable for electronics, optics, or 
  anhydrous chemical synthesis

Primary Industrial Applications

1. Electronics Manufacturing and PCB Cleaning
IPA 99.9% is the dominant cleaning solvent in the global 
electronics manufacturing industry. Its primary 
applications include printed circuit board (PCB) cleaning 
to remove flux residues after soldering, component 
degreasing before assembly, solder mask cleaning, 
conformal coating removal, and precision cleaning of 
electronic connectors and contact surfaces. At 99.9% 
purity it leaves no ionic or aqueous residue that could 
compromise electronic circuit performance or cause 
corrosion. In semiconductor wafer fabrication, IPA 
is used in wafer cleaning sequences, photoresist 
processing, and precision rinse steps.

2. Lithium-Ion Battery Manufacturing
In lithium-ion battery production, IPA 99.9% is used 
for cleaning electrode components, separator materials, 
and battery casing surfaces prior to assembly. The 
strict moisture control requirements of lithium-ion 
cell manufacturing make anhydrous IPA the only 
acceptable cleaning solvent — even trace water content 
from lower-purity IPA can compromise cell electrochemistry 
and reduce battery performance and longevity.

3. Pharmaceutical Manufacturing
In pharmaceutical production, IPA 99.9% serves as a 
process solvent, extraction agent, granulation solvent, 
equipment cleaning agent, and API recrystallisation 
solvent. Its rapid evaporation and low residue profile 
make it preferred for equipment cleaning validation 
in GMP-regulated pharmaceutical manufacturing 
environments. It is also used as a solvent in the 
manufacture of pharmaceutical tablets, capsules, 
and topical formulations.

4. Optical and Precision Component Cleaning
IPA 99.9% is the standard cleaning solvent for optical 
components including lenses, prisms, mirrors, laser 
optics, and precision instruments. Its fast, residue-free 
evaporation leaves optical surfaces clean and streak-free. 
It is used in the manufacture and maintenance of cameras, 
microscopes, telescopes, laser systems, and optical 
communication components.

5. Laboratory and Analytical Use
In research and analytical laboratories, IPA 99.9% 
is used as a general-purpose solvent for sample 
preparation, instrument cleaning, glassware rinsing, 
and reagent preparation. Its purity and consistency 
make it suitable for analytical applications where 
solvent impurities could interfere with measurements 
or assay results.

6. Cosmetic and Personal Care Manufacturing
IPA 99.9% is used in cosmetic and personal care 
manufacturing as a solvent, carrier, and antimicrobial 
agent in products including hand sanitisers, perfumes, 
aftershaves, astringents, and topical skin care products. 
Its rapid evaporation rate and skin-compatible profile 
make it a preferred solvent in cosmetic formulations 
requiring quick-dry characteristics.

Storage Requirements

Store in tightly sealed UN-approved containers at 
5-30 deg C in a dedicated flammable liquid storage 
area away from all ignition sources, heat, and direct 
sunlight. Separate from oxidising agents, peroxides, 
and reactive metals. Keep containers sealed when not 
in use to prevent evaporation and moisture absorption. 
UN 1219 transport regulations apply to all international 
shipments. Use grounding straps when transferring 
large volumes to prevent static discharge ignition.
