3'H-Spiro[cyclohexane-1,1'-isobenzofuran]-3'-one CAS 5651-49-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3'H-Spiro[cyclohexane-1,1'-isobenzofuran]-3'-one.

3'H-Spiro[cyclohexane-1,1'-isobenzofuran]-3'-one (CAS 5651-49-0), molecular formula C13H14O2 and molecular weight 202.25 g/mol, is a CATO reference standard with documented purity and traceability.

3'H-Spiro[cyclohexane-1,1'-isobenzofuran]-3'-one (C13H14O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 3'H-Spiro[cyclohexane-1,1'-isobenzofuran]-3'-one 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.
