Chemical Structure
Description
The occurrence of 1,1,1-Tris(4-hydroxyphenyl)ethane is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,1,1-Tris(4-hydroxyphenyl)ethane (CAS 27955-94-8), a certified reference material (molecular formula C20H18O3, MW 306.36 g/mol) for analytical method development and quality control.
Structurally, 1,1,1-Tris(4-hydroxyphenyl)ethane (C20H18O3) 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 306.36 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.
As a certified reference material (CRM), 1,1,1-Tris(4-hydroxyphenyl)ethane 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.
