Dalilesen impurity 54 CAS CATO-C4X-301054

Description

The occurrence of Dalilesen impurity 54 is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Dalilesen impurity 54 (CAS CATO-C4X-301054) is a certified pharmaceutical impurity reference standard with the molecular formula C13H16ClN3 and a molecular weight of 249.74 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, Dalilesen impurity 54 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 249.74 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.

CATO manufactures Dalilesen impurity 54 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.
