Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 652145-28-3 [(5Z)-5-({4-[4-(2,2-Diphenylethenyl)phenyl]-1,2,3,3a,4,8b-hexahydrocyclopenta[b]indol-7-yl}methylidene)-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]acetic acid DTXSID70728325.

652145-28-3 [(5Z)-5-({4-[4-(2,2-Diphenylethenyl)phenyl]-1,2,3,3a,4,8b-hexahydrocyclopenta[b]indol-7-yl}methylidene)-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]acetic acid DTXSID70728325 (CAS 652145-28-3) is a high-purity analytical reference standard with the molecular formula C37H30N2O3S2 and a molecular weight of 614.78 g/mol.

The molecular framework of 652145-28-3 [(5Z)-5-({4-[4-(2,2-Diphenylethenyl)phenyl]-1,2,3,3a,4,8b-hexahydrocyclopenta[b]indol-7-yl}methylidene)-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]acetic acid DTXSID70728325 (C37H30N2O3S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
