3-Chloro-2-[(E)-2-{[4-(2,4-dichlorobenzoyl)-1-methyl-1H-pyrrol-2-yl]methylidene}hydrazin-1-yl]-5-(trifluoromethyl)pyridine CAS 338795-39-4

Description

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.

3-Chloro-2-[(E)-2-{[4-(2,4-dichlorobenzoyl)-1-methyl-1H-pyrrol-2-yl]methylidene}hydrazin-1-yl]-5-(trifluoromethyl)pyridine (CAS 338795-39-4), molecular formula C19H12Cl3F3N4O and molecular weight 475.68 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Chloro-2-[(E)-2-{[4-(2,4-dichlorobenzoyl)-1-methyl-1H-pyrrol-2-yl]methylidene}hydrazin-1-yl]-5-(trifluoromethyl)pyridine (C19H12Cl3F3N4O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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).

As a certified reference material (CRM), 3-Chloro-2-[(E)-2-{[4-(2,4-dichlorobenzoyl)-1-methyl-1H-pyrrol-2-yl]methylidene}hydrazin-1-yl]-5-(trifluoromethyl)pyridine 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.
