Chemical Structure

MK 8666 CAS 1544739-75-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies MK 8666 (CAS 1544739-75-4), a certified reference material (molecular formula C29H31NO6S, MW 521.62 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, MK 8666 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 521.62 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).

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.
