Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 61319-46-8 J80FCO23IT 16-epi-Clobetasol UNII-J80FCO23IT Pregna-1,4-diene-3,20-dione, 21-chloro-9-fluoro-11,17-dihydroxy-16-methyl-, (11beta,16alpha)-).

CATO supplies 61319-46-8 J80FCO23IT 16-epi-Clobetasol UNII-J80FCO23IT Pregna-1,4-diene-3,20-dione, 21-chloro-9-fluoro-11,17-dihydroxy-16-methyl-, (11beta,16alpha)-) (CAS 61319-46-8), a certified reference material (molecular formula C22H28ClFO4, MW 410.91 g/mol) for analytical method development and quality control.

Based on its molecular formula C22H28ClFO4, 61319-46-8 J80FCO23IT 16-epi-Clobetasol UNII-J80FCO23IT Pregna-1,4-diene-3,20-dione, 21-chloro-9-fluoro-11,17-dihydroxy-16-methyl-, (11beta,16alpha)-) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 410.91 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 61319-46-8 J80FCO23IT 16-epi-Clobetasol UNII-J80FCO23IT Pregna-1,4-diene-3,20-dione, 21-chloro-9-fluoro-11,17-dihydroxy-16-methyl-, (11beta,16alpha)-) 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.
