871949-32-5 67N9QT9KEZ 27-Hydroxywithanone UNII-67N9QT9KEZ 27-Hydroxy withanone 27-Hydroxywithanone (constituent of ashwagandha root) [DSC] CAS 871949-32-5 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 871949-32-5 67N9QT9KEZ 27-Hydroxywithanone UNII-67N9QT9KEZ 27-Hydroxy withanone 27-Hydroxywithanone (constituent of ashwagandha root) [DSC].

871949-32-5 67N9QT9KEZ 27-Hydroxywithanone UNII-67N9QT9KEZ 27-Hydroxy withanone 27-Hydroxywithanone (constituent of ashwagandha root) [DSC] (CAS 871949-32-5) is a high-purity analytical reference standard with the molecular formula C28H38O7 and a molecular weight of 486.60 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 871949-32-5 67N9QT9KEZ 27-Hydroxywithanone UNII-67N9QT9KEZ 27-Hydroxy withanone 27-Hydroxywithanone (constituent of ashwagandha root) [DSC] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 486.60 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.

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.
