East Harbour Group is a trusted global distributor of Glacial Acetic Acid, the high-purity, water-free form of acetic acid used in critical applications across chemical manufacturing, pharmaceuticals, textiles, and laboratories. Our product offers 99.5%+ purity and is backed by expert knowledge, technical assurance, and regulatory compliance. We help manufacturers reduce supply chain risks and maintain continuous production by delivering consistent, high-grade chemical materials with full safety documentation and global shipping capabilities. Glacial acetic acid is the concentrated, anhydrous (less than 1% water) form of Acetic Acid. It has the same chemical formula as Acetic Acid, CH₃COOH. It is called ‘glacial’ because it can form solid acetic acid crystals at slightly cooler than room temperature at 16.7°C. Unlike Acetic Acid, Glacial Acetic Acid is not naturally occuring, and has a wide variety of uses, from being used in the production of synthetic fibres to its use in laboratories to test blood.

What is the CAS Number of Glacial Acetic Acid?
Chemicals with the same formula always share the same CAS (Chemical Abstracts Service) number, and therefore, glacial acetic acid shares the same CAS as a
Acetic Acid, which is 64-19-7. This unique identifier is used to identify a specific chemical compound and is widely recognised in chemical databases and regulatory systems. It is a clear, colourless liquid with a very strong odour of vinegar.
What is the UN Number of Glacial Acetic Acid?
The UN number for Glacial Acetic Acid is UN2790, which is the same as the UN number for Acetic Ccid of various concentrations. The UN number is an internationally recognised identifier assigned by the United Nations to hazardous substances or articles during transportation. UN2790 specifically refers to "Acetic Acid Solution" and is used for solutions of Acetic Acid with varying concentrations, including Glacial Acetic Acid. It helps in the identification and classification of the substance for transport and regulatory purposes.
What is the Hazard Class and packing group of Glacial Acetic Acid?
Much like Acetic Acid, Glacial Acetic Acid is inhazard Class 8, which indicates that Glacial Acetic Acid is corrosive. It has the potential to cause severe damage to the skin, eyes, and other materials it comes into contact with. It is assigned to Packing Group II E, which signifies a medium level of danger.

Applications of Glacial Acetic Acid
Glacial Acetic Acid is valued for its high purity and anhydrous nature, which are essential in moisture-sensitive processes and formulations.
Chemical Synthesis and Intermediates
Used as a feedstock in the production of vinyl acetate monomer (VAM), acetic anhydride, and ester-based solvents.
Pharmaceutical Manufacturing
Functions as a reagent and solvent in the synthesis of active ingredients and specialty formulations requiring stringent purity standards.
Textile and Fibre Processing
Enables dyeing, printing, and synthetic fibre production such as cellulose acetate and rayon, where water-free conditions are necessary.
Laboratory and Analytical Use
Commonly used as a solvent and reagent in controlled laboratory settings due to its predictable behaviour in anhydrous conditions.
Specialised Industrial Use
Supports production in sectors such as rubber processing, ink and dye manufacturing, and agricultural formulations (herbicides, pesticides).
