Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 348.29 g/mol gives Tamsulosin Impurity 13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tamsulosin Impurity 13 (CAS 35193-64-7), a certified reference material (molecular formula C20H13O4P, MW 348.29 g/mol) for analytical method development and quality control.
Structurally, Tamsulosin Impurity 13 (C20H13O4P) contains a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 348.29 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Tamsulosin Impurity 13 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.
