For professionals in the pharmaceutical and chemical synthesis sectors, a deep understanding of the chemical and physical properties of key intermediates is essential. 1-((4-Aminobenzenemethane)sulfonyl)pyrrolidine, identified by CAS 334981-10-1, is one such compound, vital for the production of Almotriptan. Let's explore its characteristics.

Chemically, 1-((4-Aminobenzenemethane)sulfonyl)pyrrolidine has the molecular formula C11H16N2O2S and a molecular weight of approximately 240.32 g/mol. Its structure features an aniline group, a sulfonyl group, and a pyrrolidine ring, which are critical for its reactivity in subsequent synthetic steps. The presence of the amine group makes it a versatile intermediate for further functionalization.

Physically, the compound is typically described as a pale yellow solid. Its melting point ranges from 170-176°C, indicating a relatively stable solid form under standard laboratory conditions. The density is reported around 1.31 g/cm³, and a predicted boiling point of 434.2°C at 760 mmHg suggests a high thermal stability, though practical handling often involves milder conditions.

Safe handling and storage are paramount. The material safety data sheet (MSDS) indicates that it should be stored in a cool, dry, and well-ventilated place, with containers kept tightly closed. As with many organic chemical intermediates, appropriate personal protective equipment (PPE), such as gloves, safety glasses, and lab coats, should be used when handling to avoid contact and inhalation. Its GHS classification often includes hazard statements like H315 (Causes skin irritation) and H319 (Causes serious eye irritation), underscoring the need for careful handling.

Manufacturers and researchers rely on accurate data for CAS 334981-10-1 to optimize synthetic pathways and ensure process safety. Understanding these properties allows for efficient sourcing and integration into complex manufacturing workflows, ultimately contributing to the reliable production of pharmaceuticals like Almotriptan.
