奥氮平杂质9 CAS 2554975-45-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 306.32 g/mol gives 奥氮平杂质9 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 奥氮平杂质9 (CAS 2554975-45-8), a pharmacopoeial impurity reference standard (molecular formula C17H14N4O2, MW 306.32 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, 奥氮平杂质9 (C17H14N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 306.32 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), 奥氮平杂质9 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.
