1,3,5-Trimethyl-1,1,3,5,5-pentaphenyltrisiloxane CAS 3390-61-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3,5-Trimethyl-1,1,3,5,5-pentaphenyltrisiloxane.

1,3,5-Trimethyl-1,1,3,5,5-pentaphenyltrisiloxane (CAS 3390-61-2), molecular formula C33H34O2Si3 and molecular weight 546.88 g/mol, is a CATO reference standard with documented purity and traceability.

1,3,5-Trimethyl-1,1,3,5,5-pentaphenyltrisiloxane (C33H34O2Si3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 1,3,5-Trimethyl-1,1,3,5,5-pentaphenyltrisiloxane 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.
