Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 304.40 g/mol gives 2-Methoxy-<SUP>13</SUP>C,d<SUB>3</SUB>-estradiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Methoxy-<SUP>13</SUP>C,d<SUB>3</SUB>-estradiol (CAS 1217460-84-8) is a high-purity analytical reference standard with the molecular formula C18[13C]H21D3O3 and a molecular weight of 304.40 g/mol.
The molecular framework of 2-Methoxy-<SUP>13</SUP>C,d<SUB>3</SUB>-estradiol (C18[13C]H21D3O3) is characterized by deuterium isotope labeling, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Methoxy-<SUP>13</SUP>C,d<SUB>3</SUB>-estradiol 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.
