Description
As a certified reference material (CRM), 1,1,3-Trimethyl-3-phenyl-2,3-dihydro-1H-indene 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.
CATO supplies 1,1,3-Trimethyl-3-phenyl-2,3-dihydro-1H-indene (CAS 3910-35-8), a certified reference material (molecular formula C18H20, MW 236.35 g/mol) for analytical method development and quality control.
Structurally, 1,1,3-Trimethyl-3-phenyl-2,3-dihydro-1H-indene (C18H20) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 236.35 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.
