Chemical Structure
Description
As a certified reference material (CRM), 2-(4-Butoxyphenyl)quinoline-4-carbohydrazide 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.
CATO supplies 2-(4-Butoxyphenyl)quinoline-4-carbohydrazide (CAS 51842-80-9), a certified reference material (molecular formula C20H21N3O2, MW 335.40 g/mol) for analytical method development and quality control.
The molecular framework of 2-(4-Butoxyphenyl)quinoline-4-carbohydrazide (C20H21N3O2) is characterized by a steroid 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.
