Finasteride, identified by the Chemical Abstracts Service (CAS) registry number 98319-26-7, stands as a critically important active pharmaceutical ingredient (API) and cosmetic raw material, particularly renowned for its efficacy in treating androgenetic alopecia, commonly known as male pattern hair loss, and benign prostatic hyperplasia (BPH), a prevalent condition affecting older men. Available in a high-purity powder form, this compound is the foundational substance for the development of various finished pharmaceutical and cosmetic products aimed at addressing these significant health concerns.

Chemically, Finasteride possesses the molecular formula C23H36N2O2 and a molecular weight of 372.54. It presents as a white solid with a melting point around 253 °C, indicating its crystalline nature and purity profile. Its solubility in water is relatively low, measured at approximately 0.70 mg/ml, a factor important for formulators when developing suitable delivery systems. Proper storage is crucial to maintain its stability and efficacy; it should be kept in a dark place, sealed in a dry environment, and stored in a freezer, ideally under -20°C, to preserve its integrity over time.

The therapeutic action of Finasteride centers on its role as a selective inhibitor of type II 5α-reductase. This enzyme plays a key role in steroid metabolism by converting testosterone into dihydrotestosterone (DHT), a more potent androgen. Elevated levels of DHT are implicated in the pathogenesis of both androgenetic alopecia, where it contributes to the miniaturization of hair follicles, and BPH, where it stimulates prostate growth. By inhibiting 5α-reductase, Finasteride effectively lowers serum and intraprostatic levels of DHT, thereby mitigating its adverse effects on hair follicles and prostate tissue.

In the context of hair care and anti-hair loss treatments, Finasteride powder is formulated into oral medications that have demonstrated effectiveness in promoting hair growth and preventing further hair loss on the scalp. For benign prostatic hyperplasia, it is used in pharmaceutical preparations designed to shrink the enlarged prostate, improve urinary flow rates, and alleviate associated symptoms such as frequent urination, urgency, and difficulty initiating urination. The availability of high-purity Finasteride powder is therefore essential for pharmaceutical manufacturers developing these critical medications.

Producing Finasteride powder of the requisite purity and quality for pharmaceutical and cosmetic applications requires stringent manufacturing processes and rigorous quality control. Adherence to Good Manufacturing Practices (GMP) is paramount to ensure that the final raw material is free from contaminants, has the correct chemical composition, and meets specified purity levels, often exceeding 99%. This meticulous approach to quality control is not merely a regulatory requirement but is fundamental to ensuring the safety and efficacy of the downstream products used by patients and consumers worldwide. Tests for identity, purity (including related substances and residual solvents), heavy metals, and microbial contamination are integral to the quality assurance process.

The global demand for effective treatments for hair loss and BPH continues to grow, driving the need for reliable sources of high-quality Finasteride raw material. Pharmaceutical companies and formulators rely on suppliers who can consistently provide material that meets international standards and specifications. The quality of the raw material directly impacts the stability, bioavailability, and therapeutic performance of the finished dosage forms, making the selection of a reputable source a critical business decision.
