Description

CATO supplies 7554-95-2 Cholest-5-ene-16, 3,26-bis(acetyloxy)-, (3.beta.,25R)- Cholest-5-ene-16, 3.beta.,26-dihydroxy-, diacetate, (20S,25R)- Kryptogenin-3,26-diacetate NSC-224246 NSC224246 (CAS 7554-95-2), a certified reference material (molecular formula C31H46O6, MW 514.69 g/mol) for analytical method development and quality control.

Structurally, 7554-95-2 Cholest-5-ene-16, 3,26-bis(acetyloxy)-, (3.beta.,25R)- Cholest-5-ene-16, 3.beta.,26-dihydroxy-, diacetate, (20S,25R)- Kryptogenin-3,26-diacetate NSC-224246 NSC224246 (C31H46O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 514.69 g/mol, it falls into the moderately-high-molecular-weight range. 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.
