As a certified reference material (CRM), Tolterodine Impurity 11 (O-Benzyl Tolterodine) 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.
CATO supplies Tolterodine Impurity 11 (O-Benzyl Tolterodine) (CAS 848768-06-9), a pharmacopoeial impurity reference standard (molecular formula C29H37NO, MW 415.61 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Tolterodine Impurity 11 (O-Benzyl Tolterodine) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 415.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
