Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 180152-82-3 3,6,9-Tris(carboxymethyl)-14-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)-11-oxo-3,6,9,12-tetraazatetradecanoic Acid [N-(2-Maleimidoethyl)]diethylenetriaminepentaacetic Acid Monoamide.
180152-82-3 3,6,9-Tris(carboxymethyl)-14-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)-11-oxo-3,6,9,12-tetraazatetradecanoic Acid [N-(2-Maleimidoethyl)]diethylenetriaminepentaacetic Acid Monoamide (CAS 180152-82-3), molecular formula C20H29N5O11 and molecular weight 515.47 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 180152-82-3 3,6,9-Tris(carboxymethyl)-14-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)-11-oxo-3,6,9,12-tetraazatetradecanoic Acid [N-(2-Maleimidoethyl)]diethylenetriaminepentaacetic Acid Monoamide (C20H29N5O11) is characterized by a flavonoid core, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 180152-82-3 3,6,9-Tris(carboxymethyl)-14-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)-11-oxo-3,6,9,12-tetraazatetradecanoic Acid [N-(2-Maleimidoethyl)]diethylenetriaminepentaacetic Acid Monoamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
