Description
As a certified reference material (CRM), 【禁售不询】Methylphenobarbital - * psy (M1700000) 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 【禁售不询】Methylphenobarbital - * psy (M1700000) (CAS 115-38-8), a certified reference material (molecular formula C13H14N2O3, MW 246.26 g/mol) for analytical method development and quality control.
The molecular framework of 【禁售不询】Methylphenobarbital - * psy (M1700000) (C13H14N2O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
