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 (1S,2S)-4,4-difluoro-2-(methoxycarbonyl)cyclohexane-1-carboxylic acid.
(1S,2S)-4,4-difluoro-2-(methoxycarbonyl)cyclohexane-1-carboxylic acid (CAS 2231663-93-5), molecular formula C9H12F2O4 and molecular weight 222.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (1S,2S)-4,4-difluoro-2-(methoxycarbonyl)cyclohexane-1-carboxylic acid (C9H12F2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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 222.19 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), (1S,2S)-4,4-difluoro-2-(methoxycarbonyl)cyclohexane-1-carboxylic acid 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.
