19980-43-9 (1-Cyclopenten-1-yloxy)trimethylsilane Cyclopentene, 1-((trimethylsilyl)oxy)- Silane, (1-cyclopenten-1-yloxy)trimethyl- EINECS 243-448-4 1-(Trimethylsiloxy)-1-cyclopentene CAS 19980-43-9 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 19980-43-9 (1-Cyclopenten-1-yloxy)trimethylsilane Cyclopentene, 1-((trimethylsilyl)oxy)- Silane, (1-cyclopenten-1-yloxy)trimethyl- EINECS 243-448-4 1-(Trimethylsiloxy)-1-cyclopentene.

19980-43-9 (1-Cyclopenten-1-yloxy)trimethylsilane Cyclopentene, 1-((trimethylsilyl)oxy)- Silane, (1-cyclopenten-1-yloxy)trimethyl- EINECS 243-448-4 1-(Trimethylsiloxy)-1-cyclopentene (CAS 19980-43-9) is a high-purity analytical reference standard with the molecular formula C8H16OSi and a molecular weight of 156.30 g/mol.

The molecular framework of 19980-43-9 (1-Cyclopenten-1-yloxy)trimethylsilane Cyclopentene, 1-((trimethylsilyl)oxy)- Silane, (1-cyclopenten-1-yloxy)trimethyl- EINECS 243-448-4 1-(Trimethylsiloxy)-1-cyclopentene (C8H16OSi) is characterized by a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
