Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 173.01 g/mol gives Phloroglucinol Impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Phloroglucinol Impurity 15 (CAS 95-56-7) is a certified pharmaceutical impurity reference standard with the molecular formula C6H5BrO and a molecular weight of 173.01 g/mol.
Structurally, Phloroglucinol Impurity 15 (C6H5BrO) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 173.01 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Phloroglucinol Impurity 15 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.
