Cilnidipine impurity 20 CAS CATO-C4X-179620

Description

Compared with other compounds in its class, the molecular weight of 216.23 g/mol gives Cilnidipine impurity 20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Cilnidipine impurity 20 (CAS CATO-C4X-179620), a pharmacopoeial impurity reference standard (molecular formula C13H12O3, MW 216.23 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Cilnidipine impurity 20 (C13H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 216.23 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures Cilnidipine impurity 20 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
