Description

The occurrence of 98185-20-7 EXZ5FGZ55J Raclopride tartrate Benzamide, 3,5-dichloro-N-((1-ethyl-2-pyrrolidinyl)methyl)-2-hydroxy-6-methoxy-, (S)-, (R-(R*,R*))-2,3-dihydroxybutanedioate (1:1) (salt) (S)-(-)-3,5-Dichloro-N-((1-ethyl-2-pyrrolidinyl)methyl)-6-methoxysalicylamide L-(+)-tartrate UNII-EXZ5FGZ55J is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

98185-20-7 EXZ5FGZ55J Raclopride tartrate Benzamide, 3,5-dichloro-N-((1-ethyl-2-pyrrolidinyl)methyl)-2-hydroxy-6-methoxy-, (S)-, (R-(R*,R*))-2,3-dihydroxybutanedioate (1:1) (salt) (S)-(-)-3,5-Dichloro-N-((1-ethyl-2-pyrrolidinyl)methyl)-6-methoxysalicylamide L-(+)-tartrate UNII-EXZ5FGZ55J (CAS 98185-20-7), molecular formula C15H21Cl2N2O3C4H5O6 and molecular weight 497.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 98185-20-7 EXZ5FGZ55J Raclopride tartrate Benzamide, 3,5-dichloro-N-((1-ethyl-2-pyrrolidinyl)methyl)-2-hydroxy-6-methoxy-, (S)-, (R-(R*,R*))-2,3-dihydroxybutanedioate (1:1) (salt) (S)-(-)-3,5-Dichloro-N-((1-ethyl-2-pyrrolidinyl)methyl)-6-methoxysalicylamide L-(+)-tartrate UNII-EXZ5FGZ55J (C15H21Cl2N2O3C4H5O6) is characterized by a flavonoid core, an amide 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. 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.
