Chemical Structure

1-{4h,5h,6h-cyclopenta[b]thiophene-2-carbonyl}-4-(3,4-dihydro-2h-1,5-benzodioxepine-7-sulfonyl)piperazine CAS 878211-12-2 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 1-{4h,5h,6h-cyclopenta[b]thiophene-2-carbonyl}-4-(3,4-dihydro-2h-1,5-benzodioxepine-7-sulfonyl)piperazine.

CATO supplies 1-{4h,5h,6h-cyclopenta[b]thiophene-2-carbonyl}-4-(3,4-dihydro-2h-1,5-benzodioxepine-7-sulfonyl)piperazine (CAS 878211-12-2), a certified reference material (molecular formula C21H24N2O5S2, MW 448.56 g/mol) for analytical method development and quality control.

1-{4h,5h,6h-cyclopenta[b]thiophene-2-carbonyl}-4-(3,4-dihydro-2h-1,5-benzodioxepine-7-sulfonyl)piperazine (C21H24N2O5S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
