Glutaraldehyde 50% CAS:111-30-8 is a high-strength, liquid biocide and disinfectant. It is a solution containing 50% by weight of glutaraldehyde (C5H8O2) dissolved in water. It is one of the most widely used and effective chemicals for cold sterilization and high-level disinfection.

1.Basic Information:

Molecular: C5H8O2

Appearance: Clear, colorless to pale yellow liquid.

Assay%: 50%

Ph Value: 3.5

Color (Pt/Co):15

Methanol %:0.18

Formaldehyde-Free

Odor: Pungent, characteristic irritating odor.

Solubility: Miscible with water in all proportions.

 

2. Primary Function: High-Level Disinfection and Sterilization

Glutaraldehyde 50% is renowned for its potent, broad-spectrum antimicrobial activity. It is effective against:

Bacteria (including tubercle bacilli and antibiotic-resistant strains)

Viruses (both enveloped and non-enveloped, such as HIV, HBV, and coronaviruses)

 

Its major advantage is that it achieves sterilization (the complete elimination of all microorganisms, including spores) with prolonged immersion time (typically 10+ hours), and high-level disinfection (elimination of all microorganisms except high numbers of bacterial spores) with shorter contact times (e.g., 20-45 minutes), all without requiring heat.

 

3.Applications

Water Treatment:Used as a potent biocide in industrial cooling water systems, oilfield water injection systems, and pipelines to control microbial growth (bacteria, algae, sulfate-reducing bacteria).

Healthcare and Medicine:Cold Sterilization: Immersion of heat-sensitive medical, surgical, and dental instruments (e.g., endoscopes, bronchoscopes, laparoscopes).

Disinfection of Surfaces: Used on non-porous surfaces in laboratory and clinical settings.

Other Industrial Uses:Tanning Agent: In the leather industry.

Cross linking Agent: For polymers, gels, and in tissue fixation for electron microscopy.

Preservative: In some cosmetics and personal care products.

 

4.Handling and Safety 

Glutaraldehyde 50% is a hazardous chemical and must be handled with extreme care.

Store in a cool, well-ventilated area in a tightly closed container made of compatible material (e.g., polyethylene or glass).

It is typically stabilized with specific compounds to prevent polymerization and maintain efficacy.

 

5.Package

1100KG/IBC,22T/20’FCL or 220KG/Drum,17.6T/20’FCL without pallets.


6.Summary

The 50% Glutaraldehyde (CAS: 111-30-8) is a highly efficient and versatile but potentially hazardous chemical. It is indispensable in medical disinfection and histological fixation, but its strong reactivity also means that strict safety protocols must be adhered to.
