Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 28971-58-6 67N58AU0IZ Acrocinonide [INN:DCF] Acrocinonide Triamcinolonacroleinid 9-Fluoro-11beta,16alpha,17,21-tetrahydroxypregna-1,4-diene-3,20-dione cyclic 16,17-acetal with acrolein 9-Fluor-11beta,21-dihydroxy-16alpha,17alpha-(2-propenylidenedioxy)-1,4-pregnadien-3,20-dion Acrocinonidum Acrocinonida Acrocinonid SD 2102-18 UNII-67N58AU0IZ.

CATO supplies 28971-58-6 67N58AU0IZ Acrocinonide [INN:DCF] Acrocinonide Triamcinolonacroleinid 9-Fluoro-11beta,16alpha,17,21-tetrahydroxypregna-1,4-diene-3,20-dione cyclic 16,17-acetal with acrolein 9-Fluor-11beta,21-dihydroxy-16alpha,17alpha-(2-propenylidenedioxy)-1,4-pregnadien-3,20-dion Acrocinonidum Acrocinonida Acrocinonid SD 2102-18 UNII-67N58AU0IZ (CAS 28971-58-6), a certified reference material (molecular formula C24H29FO6, MW 432.48 g/mol) for analytical method development and quality control.

Based on its molecular formula C24H29FO6, 28971-58-6 67N58AU0IZ Acrocinonide [INN:DCF] Acrocinonide Triamcinolonacroleinid 9-Fluoro-11beta,16alpha,17,21-tetrahydroxypregna-1,4-diene-3,20-dione cyclic 16,17-acetal with acrolein 9-Fluor-11beta,21-dihydroxy-16alpha,17alpha-(2-propenylidenedioxy)-1,4-pregnadien-3,20-dion Acrocinonidum Acrocinonida Acrocinonid SD 2102-18 UNII-67N58AU0IZ contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 432.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
