Trazodone is a synthetic antidepressant compound classified as a serotonin antagonist and reuptake inhibitor (SARI). It is primarily used in pharmaceutical research and as an active pharmaceutical ingredient (API) for treating major depressive disorder by modulating neurotransmitters such as serotonin in the brain, thereby improving mood, sleep, and energy levels. Off-label applications include its use for insomnia due to sedative effects at lower doses. It is also studied for managing anxiety disorders and alleviating symptoms of chronic pain conditions like fibromyalgia. This high-purity reagent (>99%) is suitable for laboratory and analytical purposes, including synthesis, spectroscopy (IR, NMR), and purity assessments. For research use only; not intended for human or veterinary therapeutic use. Use under professional supervision to ensure safety and compliance.
