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 (2R,3R,4R)-2-((1,3-Dioxolan-2-yl)methyl)-4-((triisopropylsilyl)oxy)-3-vinylcyclopentanone.
(2R,3R,4R)-2-((1,3-Dioxolan-2-yl)methyl)-4-((triisopropylsilyl)oxy)-3-vinylcyclopentanone (CAS 2764760-22-5), molecular formula C20H36O4Si and molecular weight 368.58 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2R,3R,4R)-2-((1,3-Dioxolan-2-yl)methyl)-4-((triisopropylsilyl)oxy)-3-vinylcyclopentanone (C20H36O4Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 368.58 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), (2R,3R,4R)-2-((1,3-Dioxolan-2-yl)methyl)-4-((triisopropylsilyl)oxy)-3-vinylcyclopentanone 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.
