Chemical Structure
Description
Flutoprazepam (1.0mg/ml in Acetonitrile) (CAS 25967-29-7) is a high-purity analytical reference standard with the molecular formula C19H16ClFN2O and a molecular weight of 342.79 g/mol.
Structurally, Flutoprazepam (1.0mg/ml in Acetonitrile) (C19H16ClFN2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 342.79 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Flutoprazepam (1.0mg/ml in Acetonitrile) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
