Chemical Structure

Estrone-d4 3-Sulfate Sodium Salt CAS 285979-80-8 chemical structure

Description

Estrone-d4 3-Sulfate Sodium Salt (CAS 285979-80-8), molecular formula C18H17D4O5SNa and molecular weight 376.44 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to deuterium isotope labeling, a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, Estrone-d4 3-Sulfate Sodium Salt is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 376.44 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
