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 194874-06-1 (12R,13R)-12-Hydroxy-13-methyl-20-oxo-1-oxacycloicosa-8,10,14,16,18-pentaene-2,4,5-triyl DTXSID90849586.
194874-06-1 (12R,13R)-12-Hydroxy-13-methyl-20-oxo-1-oxacycloicosa-8,10,14,16,18-pentaene-2,4,5-triyl DTXSID90849586 (CAS 194874-06-1), molecular formula C58H96O21 and molecular weight 1129.37 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 194874-06-1 (12R,13R)-12-Hydroxy-13-methyl-20-oxo-1-oxacycloicosa-8,10,14,16,18-pentaene-2,4,5-triyl DTXSID90849586 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1129.37 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.
