Minoxidil
Minoxidil (CAS: 38304-91-5), a pyrimidine derivative with the formula C9H15N5O, is a bioactive small molecule primarily recognised for its vasodilatory properties. Initially developed as an antihypertensive agent, it is now widely employed topically for the treatment of androgenetic alopecia. Its mechanism involves stimulating hair follicles and prolonging the anagen growth phase. Supplied by Tech Serve Solutions for research and development purposes, Minoxidil is a key compound in cell biology and ion channel research.

Androgenetic Alopecia Treatment
Minoxidil is extensively used in topical formulations to promote hair regrowth in individuals experiencing male and female pattern baldness. It helps to revitalise hair follicles and increase their size, leading to thicker and fuller hair.
Vasodilator Research
Originally investigated for its potent vasodilatory effects, Minoxidil serves as a valuable tool in cardiovascular research. It helps scientists understand the mechanisms of blood pressure regulation and related physiological processes.
Ion Channel Modulation Studies
As a modulator of potassium channels, Minoxidil is utilised in studies focusing on cellular signalling pathways and the function of voltage-gated ion channels. This research contributes to understanding various physiological and pathological conditions.
