Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1H-Indene, 2,3-dihydro-1,1-dimethyl-.
1H-Indene, 2,3-dihydro-1,1-dimethyl- (CAS 4912-92-9), molecular formula C11H14 and molecular weight 146.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an aromatic ring system, 1H-Indene, 2,3-dihydro-1,1-dimethyl- is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 1H-Indene, 2,3-dihydro-1,1-dimethyl- 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.
