Acetic Acid Glacial Technical

Product Overview

Acetic Acid Glacial Technical is a colorless, hygroscopic liquid with a pungent odor, representing a highly concentrated form of acetic acid (CH₃COOH). This ACS Reagent Grade, USP-NF Monograph-compliant product is supplied at 99.5–100.5% assay by titration with standardized NaOH, ensuring high purity for demanding industrial and laboratory applications. The material exhibits a specific gravity around 1.049 g/mL at 20°C and a boiling range of 118–120°C, enabling predictable performance across formulation and processing workflows. Its low water content and strict impurity profile (low chloride, nitrate, sulfates, heavy metals, and trace metals) support precision applications where contaminant control is critical. This reagent is typically stored under inert conditions to minimize moisture pickup and maintain purity for extended shelf life.

In addition to serving as a versatile solvent and chemical reagent, Acetic Acid Glacial Technical plays a key role in pH adjustment, organic synthesis, and as a preservative in suitable matrices. The product meets established standards (ACS Reagent Grade; USP-NF Monograph), reinforcing its suitability for both industrial production and analytical laboratories. The material’s physical properties, along with its stringent specification set, enable reliable, repeatable results in process streams, analytical calibrations, and quality control testing.

Safety Precautions

First safety paragraph: Handle Acetic Acid Glacial Technical in a dedicated chemical handling area with appropriate ventilation. Use chemical resistant gloves, splash-rated goggles, and a lab coat or apron. Store in HDPE or glass containers in a cool, dry, well-ventilated area away from incompatibles (oxidizers, bases). Keep containers tightly closed to minimize moisture absorption and maintain purity; use secondary containment to mitigate spills. Follow storage guidelines to prevent exposure to heat and light, and ensure compatibility with storage materials per SDS recommendations.

Second safety paragraph: This material is classified as corrosive (safety data indicate potential for skin and eye damage) and requires exposure controls and emergency procedures per OSHA/GHS. In case of contact with skin or eyes, rinse immediately with copious water for at least 15 minutes and seek medical attention. If inhaled or ingested, follow SDS-recommended first aid and contact poison control or medical professionals. Use appropriate spill response measures, neutralization where permitted, and proper waste disposal in accordance with local, state, and federal regulations. UN 2789, Acetic acid, Class 8, Packing Group II applies to transport; observe all shipping requirements and MSDS guidance during handling and transport.
