Dienestrol-3′,3

Description

CATO manufactures Dienestrol-3′,3",5′,5"-d<SUB>4</SUB> 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.

Dienestrol-3′,3",5′,5"-d<SUB>4</SUB> (CAS 1313738-05-4) is a high-purity analytical reference standard with the molecular formula C18H26D4O2 and a molecular weight of 282.45 g/mol.

The molecular framework of Dienestrol-3′,3",5′,5"-d<SUB>4</SUB> (C18H26D4O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
