Levomethorphan Solution is a controlled, analytical reference standard of 3-Methoxy-17-methylmorphinan dissolved in methanol, primarily used in pharmaceutical and forensic analysis for method validation, quality control, and research. This 3 x 1.2 mL solution contains 0.1 mg/mL of levomethorphan (CAS 125-70-2) with the molecular formula C18H25NO and a molecular weight of 271.40 g/mol. Store at ambient conditions. The product carries the Danger signal word because it is toxic if swallowed, in contact with skin or if inhaled (H301 + H311 + H331) and causes damage to organs (H370), hazards that largely arise from the methanol solvent. Molekula supplies Levomethorphan Solution from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

This substance is available from Molekula on enquiry. Full specification, Safety Data Sheet and Certificate of Analysis documentation are provided with your quotation once our team confirms the grade and pack size you need.
