5-ethyl-3-phenyl-2-thioxoimidazolidin-4-one 66256-32-4 PTH-DL-2-Aminobutyric acid CAS 66256-32-4

Description

The occurrence of 5-ethyl-3-phenyl-2-thioxoimidazolidin-4-one 66256-32-4 PTH-DL-2-Aminobutyric acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-ethyl-3-phenyl-2-thioxoimidazolidin-4-one 66256-32-4 PTH-DL-2-Aminobutyric acid (CAS 66256-32-4), molecular formula C11H12N2OS and molecular weight 220.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 5-ethyl-3-phenyl-2-thioxoimidazolidin-4-one 66256-32-4 PTH-DL-2-Aminobutyric acid is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 220.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 5-ethyl-3-phenyl-2-thioxoimidazolidin-4-one 66256-32-4 PTH-DL-2-Aminobutyric 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.
