Chemical Structure

Pregnanetriol CAS 1098-45-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 336.51 g/mol gives Pregnanetriol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Pregnanetriol (CAS 1098-45-9), a certified reference material (molecular formula C21H36O3, MW 336.51 g/mol) for analytical method development and quality control.

The molecular framework of Pregnanetriol (C21H36O3) is characterized by a steroid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Pregnanetriol 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.
