Carteolol Impurity 35 CAS CATO-C4X-228735

Description

Compared with other compounds in its class, the molecular weight of 298.13 g/mol gives Carteolol Impurity 35 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Carteolol Impurity 35 (CAS CATO-C4X-228735) is a certified pharmaceutical impurity reference standard with the molecular formula C12H12BrNO3 and a molecular weight of 298.13 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Carteolol Impurity 35 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Carteolol Impurity 35 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.
