Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [1,1'-Biphenyl]-3-yltrimethylsilane.
CATO supplies [1,1'-Biphenyl]-3-yltrimethylsilane (CAS 17938-21-5), a certified reference material (molecular formula C15H18Si, MW 226.39 g/mol) for analytical method development and quality control.
Structurally, [1,1'-Biphenyl]-3-yltrimethylsilane (C15H18Si) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 226.39 g/mol, it falls into the medium-molecular-weight range. 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), [1,1'-Biphenyl]-3-yltrimethylsilane 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.
