1-{[3,5-bis(methoxycarbonyl)-4-methylthiophen-2-yl]sulfonyl}piperidine-4-carboxylic acid CAS 731003-70-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-{[3,5-bis(methoxycarbonyl)-4-methylthiophen-2-yl]sulfonyl}piperidine-4-carboxylic acid.

1-{[3,5-bis(methoxycarbonyl)-4-methylthiophen-2-yl]sulfonyl}piperidine-4-carboxylic acid (CAS 731003-70-6) is a high-purity analytical reference standard with the molecular formula C15H19NO8S2 and a molecular weight of 405.44 g/mol.

The molecular framework of 1-{[3,5-bis(methoxycarbonyl)-4-methylthiophen-2-yl]sulfonyl}piperidine-4-carboxylic acid (C15H19NO8S2) is characterized by a flavonoid core, 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.
