Description

The occurrence of 5'-Methyl-1',2'-dihydrospiro[1,3-dioxolane-2,3'-indole]-2'-one is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5'-Methyl-1',2'-dihydrospiro[1,3-dioxolane-2,3'-indole]-2'-one (CAS 75822-58-1), molecular formula C11H11NO3 and molecular weight 205.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5'-Methyl-1',2'-dihydrospiro[1,3-dioxolane-2,3'-indole]-2'-one (C11H11NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 205.21 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 5'-Methyl-1',2'-dihydrospiro[1,3-dioxolane-2,3'-indole]-2'-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.
