Chemical Structure

5-HO-EHDPP CAS 2173149-33-0 chemical structure

Description

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.

5-HO-EHDPP (CAS 2173149-33-0), molecular formula C20H27O5P and molecular weight 378.40 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage, 5-HO-EHDPP is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 378.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 5-HO-EHDPP 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.
