4-Aminophenylarsonic acid, commonly known as arsanilic acid (CAS 98-50-0), is an organoarsenic compound that demands a thorough understanding of its toxicological profile. As an arsenic derivative, it carries inherent risks, and its handling requires stringent safety protocols. Exposure to arsanilic acid can lead to a range of adverse health effects, including irritation to the skin and eyes, potential hyperpigmentation, and effects on internal organs such as the kidneys, liver, and central nervous system. Historically, occupational exposure has been linked to various poisoning symptoms, emphasizing the need for vigilance.

The toxicity classification for arsanilic acid includes being poisonous by intravenous and intraperitoneal routes and moderately toxic by ingestion. Furthermore, it is considered harmful to aquatic life, necessitating responsible disposal practices to prevent environmental contamination. When working with arsanilic acid, it is imperative to employ appropriate personal protective equipment (PPE), including chemical-resistant gloves, safety goggles or face shields, and respiratory protection, especially in environments where dust or aerosols might be present. Ensuring adequate ventilation in work areas is also crucial to maintain safe air quality. Any individual seeking to purchase arsanilic acid must be aware of these hazards and be prepared to implement comprehensive safety measures.
