About Efinaconazole

Efinaconazole (CAS 164650-44-6) is a high-purity reference standard of Efinaconazole offered by Vaqora Chemicals. Its molecular formula is C18H22F2N4O and its molecular weight is 348.4 g/mol. Its systematic (IUPAC) name is (2R,3R)-2-(2,4-difluorophenyl)-3-(4-methylidenepiperidin-1-yl)-1-(1,2,4-triazol-1-yl)butan-2-ol. Common synonyms include KP-103 and efinaconazol.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this Efinaconazole standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Vaqora Chemicals supplies Efinaconazole in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
