Chemical Structure

U 46619 CAS 56985-40-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including U 46619.

CATO supplies U 46619 (CAS 56985-40-1), a certified reference material (molecular formula C21H34O4, MW 350.49 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, U 46619 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.49 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.

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

As a certified reference material (CRM), U 46619 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.
