Chemical Structure
Description
The occurrence of 21154-48-3 Germanium tetraisopropoxide Germanium(IV) isopropoxide Isopropyl germanate(IV) Tetraisopropoxygermane Tetraisopropoxygermanium is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
21154-48-3 Germanium tetraisopropoxide Germanium(IV) isopropoxide Isopropyl germanate(IV) Tetraisopropoxygermane Tetraisopropoxygermanium (CAS 21154-48-3), molecular formula C12H28GeO4 and molecular weight 308.99 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 21154-48-3 Germanium tetraisopropoxide Germanium(IV) isopropoxide Isopropyl germanate(IV) Tetraisopropoxygermane Tetraisopropoxygermanium (C12H28GeO4) is characterized by a carboxylic acid group, 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.
CATO manufactures 21154-48-3 Germanium tetraisopropoxide Germanium(IV) isopropoxide Isopropyl germanate(IV) Tetraisopropoxygermane Tetraisopropoxygermanium under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
