Description

Compared with other compounds in its class, the molecular weight of 444.54 g/mol gives (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (4-methoxyphenyl) mesitylphosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (4-methoxyphenyl) mesitylphosphonate (CAS 1463876-67-6), a certified reference material (molecular formula C26H37O4P, MW 444.54 g/mol) for analytical method development and quality control.

The molecular framework of (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (4-methoxyphenyl) mesitylphosphonate (C26H37O4P) is characterized by a steroid core, a phosphate ester group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (4-methoxyphenyl) mesitylphosphonate 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.
