Description
CATO manufactures (3α)-Allopregnanolone-d5 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.
(3α)-Allopregnanolone-d5 (CAS CATO-CCAD302750), molecular formula C21H29D5O2 and molecular weight 323.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3α)-Allopregnanolone-d5 (C21H29D5O2) 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).
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.
