3-beta,5-beta-Tetrahydro Levonorgestrel CAS 19351-17-8 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 3-beta,5-beta-Tetrahydro Levonorgestrel.

CATO supplies 3-beta,5-beta-Tetrahydro Levonorgestrel (CAS 19351-17-8), a certified reference material (molecular formula C21H32O2, MW 316.48 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, 3-beta,5-beta-Tetrahydro Levonorgestrel is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.48 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.

As a certified reference material (CRM), 3-beta,5-beta-Tetrahydro Levonorgestrel 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.
