17Α-Estradiol-16,16,17-D3 CAS CATO-CCAD300789

Description

Compared with other compounds in its class, the molecular weight of 275.40 g/mol gives 17Α-Estradiol-16,16,17-D3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 17Α-Estradiol-16,16,17-D3 (CAS CATO-CCAD300789), a certified reference material (molecular formula C18H21D3O2, MW 275.40 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, 17Α-Estradiol-16,16,17-D3 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 275.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 17Α-Estradiol-16,16,17-D3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
