Description

Finasteride (Acetate) is a specific acetate salt form of the well-known pharmaceutical compound finasteride. This form is valued for its enhanced stability and suitability as a key intermediate in the synthesis of high-purity active pharmaceutical ingredients (APIs). It is primarily utilized by pharmaceutical manufacturers and research institutions engaged in developing and producing treatments for androgen-dependent conditions, such as benign prostatic hyperplasia (BPH) and androgenetic alopecia.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of finasteride-based active pharmaceutical ingredients (APIs).
• Research & Development: Used in biochemical and pharmacological research to study 5-α-reductase inhibition and its effects.
• Reference Standard: Serves as a certified reference material (CRM) for analytical method development and quality control in laboratories.
• Formulation Development: Employed in pre-formulation studies for developing various dosage forms, including tablets and capsules.
