Chemical Structure
Description
Estriol 16α-(β-D-Glucuronide) Sodium Salt (C24H31O9Na) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Estriol 16α-(β-D-Glucuronide) Sodium Salt (CAS 1852-44-4) is a high-purity analytical reference standard with the molecular formula C24H31O9Na and a molecular weight of 486.49 g/mol.
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.
CATO manufactures Estriol 16α-(β-D-Glucuronide) Sodium Salt 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.
