About 2-Methoxy Phenothiazine

2-Methoxy Phenothiazine (CAS 1771-18-2) is an impurity of Levomepromazine offered by Vaqora Chemicals. Formula C13H11NOS, molecular weight 229.3 g/mol. The IUPAC name is 2-methoxy-10H-phenothiazine. It is also known as Methyl phenothiazin-2-yl ether or 10H-Phenothiazine, 2-methoxy-.

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. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

As a characterised impurity of Levomepromazine, it is used for analytical method development, method validation (AMV) and routine quality-control testing, and it supports ANDA and DMF regulatory filings. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

We offer 2-Methoxy Phenothiazine in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
