Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 108.09 g/mol gives 12-methyl-12h-benzo[a]phenothiazine 813-56-9 AR-1C0686 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
12-methyl-12h-benzo[a]phenothiazine 813-56-9 AR-1C0686 (CAS 813-56-9), molecular formula C3D4O4 and molecular weight 108.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 12-methyl-12h-benzo[a]phenothiazine 813-56-9 AR-1C0686 (C3D4O4) is characterized by deuterium isotope labeling, a carboxylic acid group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
As a certified reference material (CRM), 12-methyl-12h-benzo[a]phenothiazine 813-56-9 AR-1C0686 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.
