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 (2-((9,9-Dimethyl-9H-fluoren-2-yl)dimethylsilyl)phenyl)methanol.
(2-((9,9-Dimethyl-9H-fluoren-2-yl)dimethylsilyl)phenyl)methanol (CAS 1244855-65-9), molecular formula C24H26OSi and molecular weight 358.55 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2-((9,9-Dimethyl-9H-fluoren-2-yl)dimethylsilyl)phenyl)methanol (C24H26OSi) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 358.55 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
