About Tizanidine

Vaqora Chemicals supplies Tizanidine, a high-purity reference standard of Tizanidine registered under CAS number 51322-75-9. With the molecular formula C9H8ClN5S, it has a molar mass of 253.71 g/mol. The IUPAC name is 5-chloro-N-(4,5-dihydro-1H-imidazol-2-yl)-2,1,3-benzothiadiazol-4-amine. Common synonyms include Ternelin and Tizanidine (INN).

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

Laboratories use this Tizanidine standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. It is used across pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
