Chemical Structure
Description
As a certified reference material (CRM), Ambroxol Cycloimine Impurity 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 Ambroxol Cycloimine Impurity (CAS 2088879-81-4), a pharmacopoeial impurity reference standard (molecular formula C14H16Br2N2O, MW 388.10 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Ambroxol Cycloimine Impurity (C14H16Br2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 388.10 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.
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.
