Denatured Alcohol 200 Proof 3C

Product Overview

Denatured Alcohol 200 Proof 3C is a high-purity ethanol solution that has been rendered unsuitable for human consumption by the addition of denaturants. This Technical Grade product delivers exceptional solvency and a low boiling point, making it a reliable choice for industrial and analytical workflows. With a typical assay of 99.5 wt% ethanol (GC/HPLC via internal standard), it provides consistent performance across solvent-based processes, including extraction, cleaning, and chromatographic applications. The product is designed to meet stringent industry expectations for purity, low residue on evaporation, and minimal heavy metal contamination, ensuring compatibility with sensitive chemical reactions and analytical methods. Its clear, colorless appearance and characteristic alcoholic odor are consistent with high-grade denatured ethanol used in laboratory and manufacturing environments.

In addition to its primary solvent role, this denatured ethanol supports a wide range of technical applications, from solvent extraction of active pharmaceutical ingredients to use as a mobile phase in HPLC systems and as a cleaning/degreasing solvent for industrial equipment. The product's low residue (typical 0.001%) and low aldehyde content help minimize interference in analytical methods and synthetic schemes. Proper handling, storage, and adherence to SDS guidelines are essential to maintain product integrity and safety in facility environments.

Safety Precautions

Handling and storage should follow standard laboratory practices for flammable liquids: keep in a cool, well-ventilated area away from sources of ignition, store in HDPE or glass containers, and use proper ventilation during handling to minimize inhalation exposure. Wear appropriate PPE, including chemical-resistant gloves, splash goggles, and suitable lab coats or coveralls. Grounding and bonding may be required for large volumes to prevent static discharge and vapor accumulation.

Additional safety considerations include adherence to SDS guidelines, monitoring for exposure limits, and implementing emergency response procedures for spills, inhalation, or skin/eye contact. In the event of skin or eye contact, rinse with water for several minutes and seek medical attention if irritation persists. For inhalation, move to fresh air and seek medical evaluation if symptoms occur. In case of ingestion, do not induce vomiting and obtain medical assistance immediately.

Benefits

✔ High Purity – Typical assay 99.5 wt% with low residue supports precise analytical and industrial workflows.
✔ Low Impurity Profile – Monitored aldehydes, metals, and anion contaminants minimize interference in sensitive reactions and chromatographic applications.
