Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 131.12 g/mol gives Benzo-<SUP>13</SUP>C<SUB>6</SUB>-oxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Benzo-<SUP>13</SUP>C<SUB>6</SUB>-oxazole (CAS 1216500-18-3), a certified reference material (molecular formula C[13C]6H3D4NO, MW 131.12 g/mol) for analytical method development and quality control.
The molecular framework of Benzo-<SUP>13</SUP>C<SUB>6</SUB>-oxazole (C[13C]6H3D4NO) is characterized by deuterium isotope labeling, 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. 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), Benzo-<SUP>13</SUP>C<SUB>6</SUB>-oxazole 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.
