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 Tetramethyl (cyclopent-1-ene-1,2-diylbis(5-methylthiophene-4,2-diyl))diboronate.
Tetramethyl (cyclopent-1-ene-1,2-diylbis(5-methylthiophene-4,2-diyl))diboronate (CAS 1632972-15-6) is a high-purity analytical reference standard with the molecular formula C19H26B2O4S2 and a molecular weight of 404.16 g/mol.
Based on its molecular formula C19H26B2O4S2, Tetramethyl (cyclopent-1-ene-1,2-diylbis(5-methylthiophene-4,2-diyl))diboronate contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 404.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Tetramethyl (cyclopent-1-ene-1,2-diylbis(5-methylthiophene-4,2-diyl))diboronate 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.
