Gestrinone Impurity 7 CAS 116299-92-4 chemical structure

Description

CATO manufactures Gestrinone Impurity 7 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.

Gestrinone Impurity 7 (CAS 116299-92-4) is a high-purity analytical reference standard with the molecular formula C21H28O3 and a molecular weight of 328.45 g/mol.

Gestrinone Impurity 7 (C21H28O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
