Chemical Structure
Description
As a certified reference material (CRM), Tetramethyl Risedronate 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 Tetramethyl Risedronate (CAS 919355-29-6), a certified reference material (molecular formula C11H19NO7P2, MW 339.22 g/mol) for analytical method development and quality control.
Owing to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Tetramethyl Risedronate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
