tert-Butyl(cyclopent-3-en-1-yloxy)diphenylsilane CAS 182801-94-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl(cyclopent-3-en-1-yloxy)diphenylsilane.

tert-Butyl(cyclopent-3-en-1-yloxy)diphenylsilane (CAS 182801-94-1), molecular formula C21H26OSi and molecular weight 322.52 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of tert-Butyl(cyclopent-3-en-1-yloxy)diphenylsilane (C21H26OSi) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
