Chemical Structure

Tetrahydrocortisone 3-Glucuronide CAS 26312-91-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 540.60 g/mol gives Tetrahydrocortisone 3-Glucuronide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Tetrahydrocortisone 3-Glucuronide (CAS 26312-91-4), a certified reference material (molecular formula C27H40O11, MW 540.60 g/mol) for analytical method development and quality control.

Structurally, Tetrahydrocortisone 3-Glucuronide (C27H40O11) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 540.60 g/mol, it falls into the moderately-high-molecular-weight range. 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.

As a certified reference material (CRM), Tetrahydrocortisone 3-Glucuronide 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.
