1-((4,5-Diphenyloxazol-2-yl)methyl)guanidine sulfate(2:1) CAS 33161-90-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-((4,5-Diphenyloxazol-2-yl)methyl)guanidine sulfate(2:1).

1-((4,5-Diphenyloxazol-2-yl)methyl)guanidine sulfate(2:1) (CAS 33161-90-9) is a high-purity analytical reference standard with the molecular formula C17H18N4OO4S and a molecular weight of 390.41 g/mol.

The molecular framework of 1-((4,5-Diphenyloxazol-2-yl)methyl)guanidine sulfate(2:1) (C17H18N4OO4S) is characterized by a flavonoid core, an amide group, a sulfone 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. 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.

As a certified reference material (CRM), 1-((4,5-Diphenyloxazol-2-yl)methyl)guanidine sulfate(2:1) 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.
