Chemical Structure

1.2,4,5-Di-o-isopropylidene-myo-inositol CAS 98974-89-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1.2,4,5-Di-o-isopropylidene-myo-inositol.

CATO supplies 1.2,4,5-Di-o-isopropylidene-myo-inositol (CAS 98974-89-1), a certified reference material (molecular formula C12H20O6, MW 260.28 g/mol) for analytical method development and quality control.

Structurally, 1.2,4,5-Di-o-isopropylidene-myo-inositol (C12H20O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 260.28 g/mol, it falls into the medium-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), 1.2,4,5-Di-o-isopropylidene-myo-inositol 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.
