Product Overview
Luliconazole (development code NND-502) is a synthetic azole antifungal distinguished by a unique structure in which the imidazole ring is incorporated into a ketene dithioacetate (1,3-dithiolane) framework bearing a 2,4-dichlorophenyl group. It is supplied as a white to pale yellow crystalline powder. Compared with older azoles, luliconazole offers high antifungal potency and low keratin binding, which supports activity through the stratum corneum and nail plate. It is the active ingredient in marketed topical products for tinea pedis, tinea cruris, tinea corporis and onychomycosis (nail fungal infection).
Chemical Structure

Key Advantages
Broad-spectrum activity against dermatophytes (Trichophyton), yeasts (Candida) and common molds.
High antifungal potency; low keratin binding supports skin and nail penetration.
Stable, free-flowing crystalline API suitable for hot-melt, solvent and aqueous-based topical processing.
Multi-grade availability (IP/USP/EP), consistent assay and impurity control.
Full documentation package - COA, SDS/TDS, batch certificate and export paperwork.
Applications & End Uses
6.1 Topical Antifungal Creams & Ointments
Formulated at typical 1 % concentration for tinea pedis (athlete's foot), tinea cruris (jock itch) and tinea corporis (ringworm).
6.2 Gels and Solutions
Used in alcoholic/aqueous gels and sprays for scalp and interdigital fungal infections.
6.3 Nail Lacquer / Onychomycosis Products
At higher concentrations (e.g. 5 % nail solution), luliconazole is developed for onychomycosis (fungal nail infection), leveraging its low keratin binding for nail-bed release.
6.4 Combination Dermatological Formulations
Blended with corticosteroids, keratolytics (urea) or other actives for combination anti-inflammatory / antifungal products.
6.5 Research & Reference Use
Also supplied as a reference / analytical standard for laboratories and quality-control departments.

Frequently Asked Questions (FAQ)
Q: What is luliconazole used for?
A: Luliconazole is an imidazole antifungal API used to make topical medicines for dermatophyte infections such as tinea pedis, tinea cruris, tinea corporis, and nail fungal infection (onychomycosis).
Q: What is the CAS number of luliconazole?
A: The CAS number is 187164-19-8. Its molecular formula is C14H9Cl2N3S2 and molecular weight is 354.28 g/mol.
Q: How does luliconazole work?
A: It inhibits lanosterol 14α-demethylase (CYP51), blocking ergosterol synthesis and thereby disrupting the fungal cell membrane, which stops fungal growth.
Q: What form and appearance is the API?
A: It is a white to pale yellow crystalline powder, practically insoluble in water but freely soluble in acetone and soluble in methanol/acetonitrile. It should be protected from light.
Q: What assay and grades do you offer?
A: We offer pharmaceutical (IP/USP/EP) grade at ≥98.5 % assay, CDMO production grade, and analytical reference standard, each with a full COA.
Q: What is the typical concentration in finished products?
A: Cream/gel products are commonly around 1 %, and nail solution products around 5 %, per marketed formulations. Exact formulation is the responsibility of the finished-product manufacturer.
Q: What is your MOQ and packaging?
A: Packaging ranges from 100 g to 25 kg light-protected drums; MOQ starts at [insert MOQ]. Contact us for current lead time and FOB pricing.
