Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5aR,10bS)-2-Phenyl-1,2,4,5a,6,10b-hexahydroindeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazine.

CATO supplies (5aR,10bS)-2-Phenyl-1,2,4,5a,6,10b-hexahydroindeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazine (CAS 1148001-12-0), a certified reference material (molecular formula C18H17N3O, MW 291.35 g/mol) for analytical method development and quality control.

The molecular framework of (5aR,10bS)-2-Phenyl-1,2,4,5a,6,10b-hexahydroindeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazine (C18H17N3O) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), (5aR,10bS)-2-Phenyl-1,2,4,5a,6,10b-hexahydroindeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazine 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.
