Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Benzyl(methyl)amino)-2-oxoethyl 2-(5-chlorothiophen-2-yl)quinoline-4-carboxylate.

2-(Benzyl(methyl)amino)-2-oxoethyl 2-(5-chlorothiophen-2-yl)quinoline-4-carboxylate (CAS 785705-71-7), molecular formula C24H19ClN2O3S and molecular weight 450.94 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(Benzyl(methyl)amino)-2-oxoethyl 2-(5-chlorothiophen-2-yl)quinoline-4-carboxylate (C24H19ClN2O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2-(Benzyl(methyl)amino)-2-oxoethyl 2-(5-chlorothiophen-2-yl)quinoline-4-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
