Basic Information

Acetic acid
AcOH
Colorless liquid

Acetic acid is a colorless liquid with a pungent odor, miscible with water and many organic solvents. This weak organic acid readily participates in esterification and serves as a reaction medium. Major applications include vinyl acetate, acetic anhydride, acetate salts, cellulose acetate, solvent esters, and chemical intermediates; its anhydrous form is called glacial acetic acid.

product description

Essential Organic Acid with Natural Origin:Acetic acid is a fundamental fatty acid occurring naturally in many plants and is the primary component responsible for the characteristic aroma and flavor of vinegar.


High Purity & Excellent Solubility:With the formula CH₃COOH, acetic acid is fully miscible with water and many organic solvents, offering outstanding versatility for chemical synthesis and industrial formulations.


Glacial Grade for High-End Applications:Glacial acetic acid represents the anhydrous, high-purity form that crystallizes at low temperatures, providing superior performance for pharmaceutical, chemical, and manufacturing uses.


Reactive & Historically Proven Chemical:As a weak organic acid capable of esterification reactions, acetic acid plays a vital role in organic chemistry and has a long, well-established history in both traditional and modern production.



Products Description of Acetic acid CAS#64-19-7

Acetic acid (AcOH) is the main component of vinegar, a colorless pungent liquid (mp 16.6 °C, bp 117.9 °C, density 1.049 at 20 °C) miscible with water and most organic solvents. Its anhydrous form (glacial acetic acid) is corrosive and crystallizes at low temperatures. A weak organic acid prone to esterification, it is one of the most important industrial organic acids.


Product Applications of Acetic acid CAS#64-19-7

Acetic acid is a core industrial chemical used to produce vinyl acetate, acetic anhydride, acetates and cellulose acetate (for adhesives, fibers, films). Its esters are solvents for coatings/inks; it also serves as a reaction medium, raw material for pharma/agrochemicals, metal acetate precursor, and food acidifier. Corrosive, requiring safe handling.
