75% Vinegar ACS Grade

Product Overview

75% Vinegar ACS Grade, also known as Acetic Acid Solution, is a concentrated, water-miscible acetic acid solution formulated to meet rigorous ACS reagent grade specifications. This 75% w/w formulation provides high-purity acetic acid suitable for analytical chemistry, synthesis, and process industries where reproducible acidity, trace impurity control, and consistent performance are essential. The product is supplied as a clear, colorless liquid with a pungent, vinegar-like odor and is fully miscible with water, enabling precise dilution to target pH regimes for diverse applications. Typical assay accuracy is guaranteed within an assay range of 74–76% by titration with standardized NaOH, ensuring reliable acidity for calibrated analytical methods and reaction stoichiometry.

ACS Grade status indicates conformance to established pharmaceutical- and laboratory-grade quality standards, including compliance with ACS Reagent Grade and USP-NF monographs. The formulation is controlled for low residue and minimized contamination by metal ions, supporting use in sensitive spectroscopic, chromatographic, and synthetic processes. The product is intended for industrial and institutional use, with storage and handling guidelines designed to maintain stability and purity from manufacture to application.

Safety Precautions

Handle with appropriate PPE including chemical-resistant gloves, safety goggles or face shield, and protective clothing. Store in cool, dry places away from direct sunlight in HDPE or glass containers, and ensure adequate ventilation to prevent vapor buildup. Keep away from strong oxidizers and bases; use secondary containment where required to prevent spills or leaks. Follow universal precautions and consult the SDS prior to use to implement site-specific risk controls.

In case of exposure, rinse affected skin or eyes with plenty of water for at least 15 minutes and seek medical attention if irritation persists. If inhaled, move to fresh air and seek medical care if symptoms occur. For ingestion, rinse mouth and do not induce vomiting; seek medical attention immediately. Transport is designated UN 2790, Acetic acid solution, Class 8, PG II, in compliance with applicable regulations.
