A-A-59601E Type III ACS Grade

Product Overview

A-A-59601E Type III ACS Grade is a high-purity chemical designed to meet stringent ACS specifications for analytical and industrial use. This Type III ACS-grade liquid is formulated to deliver precise composition and low impurity levels, enabling reliable performance in demanding laboratory workflows. The product demonstrates a clear, colorless appearance with odorless characteristics, and is suitable for applications requiring minimized interference from contaminants in analytical methods. Typical assay wt% falls near the upper end of the specification, supporting high-purity requirements for reproducible results in HPLC mobile phases, spectroscopy, and titrimetric procedures. The material is characterized by a controlled color, low residue after ignition, and very low water content, all of which contribute to consistent analytical performance and reduced background signals in sensitive measurements.

This ACS-grade reagent is commonly used in analytical chemistry and related sectors where traceability to established standards is essential. Its well-defined density and refractive index support quantitative analyses and method development, while the broad solubility in water and alcohol simplifies preparation of diversified solvent systems. The product's chemistry and purity profile align with industry expectations for high-purity solvents and reagents employed in chromatography, spectroscopic baselines, and reaction monitoring, making A-A-59601E Type III a dependable choice for laboratories and manufacturers requiring rigorous quality control.

Safety Precautions

Handle under normal laboratory ventilation with appropriate PPE, including chemical-resistant gloves, safety goggles, and a lab coat. Store in a cool, dry place away from direct sunlight in compatible containers such as HDPE or glass, ensuring containers are tightly closed to minimize moisture uptake and contamination. Keep away from strong oxidizers and acids, and maintain adequate ventilation to control vapor exposure.

In case of exposure, follow standard SDS procedures: for eyes, rinse cautiously with water for several minutes; for skin, wash with soap and water and seek medical advice if irritation persists; for inhalation, move to fresh air and seek medical attention if symptoms occur; for ingestion, rinse mouth and seek medical attention immediately. This product is classified under UN 1789, Hydrochloric acid, Class 8, PG II for transport considerations and requires trained handling for hazardous materials. Ensure spill response plans and eyewash stations are accessible in storage and handling areas.

Benefits

✔ ACS Grade Compliance – Meets or exceeds ACS Reagent Grade specifications (ACS Reagent Grade, 11th Edition) and USP-NF monograph expectations, ensuring high purity and traceability in analytical methods.
✔ Low Impurity Profile – Very low levels of halides, metals, and sulfates minimize interference in chromatographic and spectroscopic analyses, improving method reliability.
✔ Excellent Storage Stability – Narrow residue after ignition, minimal water content, and controlled color support consistent performance over a 24-month shelf life when stored as recommended.
