CAS 154992-24-2 Ru-58841

RU58841, also known as PSK-3841. It is a specific non-steroidal androgen receptor antagonist. Its core active ingredient is the highly pure RU58841 monomer, with the molecular formula of C₁₇H₁₈F₃N₃O₃ and a molecular weight of 369.34. The industrial commercial-grade finished product is tested by high-performance liquid chromatography (HPLC), and its purity is stable at over 98%. The purity of custom-made batches can reach up to 99.9%. During the production process, all synthetic intermediates, heavy metal residues, and solvent residues are completely removed, ensuring the stability of the active ingredient structure and preventing degradation of components and loss of efficacy. The high-quality RU58841 powder is a white powder, with fine and uniform powder. Its overall odor is mild, almost without irritating smell, and only has an extremely faint original flavor of the raw material. The solubility of RU58841 powder is compatible with the mainstream solvent systems of cosmetic products, and its dissolution characteristics are stable and controllable. It is insoluble in pure water, but easily soluble in organic solvents such as ethanol, DMSO, and DMF. It can also be stably dissolved in alcohol-water mixed systems, suitable for most liquid cosmetic formulations. After dissolution, the solution is clear and transparent, without affecting the appearance and texture of the finished product.

CAS 154992-24-2 ru-58841 can precisely bind to the androgen receptors in hair follicles on the scalp, blocking the combination of DHT with the hair follicles at the source, and completely cutting off the cause of hair loss. Compared with conventional ingredients such as minoxidil and finasteride, it does not need to regulate the overall hormone levels of the human body. It only acts on the local application area and can effectively delay the backward movement of the hairline and the thinning of the top of the head. Its improvement effect on early and middle-stage androgenetic alopecia is particularly remarkable.

CAS 154992-24-2 ru-58841 powder can effectively reverse the miniaturization state of hair follicles, awaken dormant hair follicles, and restore the normal nutrient absorption and metabolic capabilities of hair follicles. Persistent use can thicken the diameter of hair and extend the hair growth period, reduce hair loss during the resting phase, make the new hair denser and stronger, and achieve the effects of stable hair growth and hair fixation.

CAS 154992-24-2 ru-58841 can specifically improve skin problems caused by excessive androgen secretion. By locally antagonizing androgen activity, it regulates excessive sebum secretion of the sebaceous glands, reduces the accumulation of excess oil on the scalp and face, and unclogs the clogged pores. It can effectively improve oily scalp oiliness and frequent dandruff. It also has a good conditioning and repair effect on skin problems caused by androgens, such as acne and facial hirsutism, and takes into account the stability of both scalp and facial skin.

As the core active ingredient, Ru58841 is widely used in the formulation of cross-border high-end hair-strengthening serums, hair growth liquids, scalp repair sprays, and hair growth creams and other products.

Ru58841 can be added to products such as oil-control toner, acne-removing essence, and pore-repairing lotion for skin care.

Ru58841 is widely used in customized treatment plans of medical beauty institutions and scalp management centers. It can be formulated into scalp care preparations specifically for medical clinics and skin control and repair solutions.

Ru58841 is commonly used in research projects such as hair loss pharmacological studies, development of anti-androgen drugs, and exploration of the mechanism of skin oil control.
