Description

As a certified reference material (CRM), 2-(2-Amino-6-(4-((cyclohexylmethyl)amino)-4-oxobutoxy)quinazolin-3(4H)-yl)acetic acid 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.

2-(2-Amino-6-(4-((cyclohexylmethyl)amino)-4-oxobutoxy)quinazolin-3(4H)-yl)acetic acid (CAS 114703-77-4), molecular formula C21H30N4O4 and molecular weight 402.49 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(2-Amino-6-(4-((cyclohexylmethyl)amino)-4-oxobutoxy)quinazolin-3(4H)-yl)acetic acid (C21H30N4O4) 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.
