Chemical Structure
Description
The occurrence of Chlorhexidine Impurity 23 is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Chlorhexidine Impurity 23 (CAS CATO-C4X-225623), a pharmacopoeial impurity reference standard (molecular formula C14H33N7, MW 299.46 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Chlorhexidine Impurity 23 (C14H33N7) contains a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 299.46 g/mol, it falls into the medium-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), Chlorhexidine Impurity 23 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.
