Chemical Structure
Description
As a certified reference material (CRM), MB-07811 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.
MB-07811 (CAS 852948-13-1), molecular formula C28H32ClO5P and molecular weight 514.98 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of MB-07811 (C28H32ClO5P) is characterized by a steroid core, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
