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 7β-Hydroxycholesterol-25,26,26,26,27,27,27-d7.
7β-Hydroxycholesterol-25,26,26,26,27,27,27-d7 (CAS 349553-97-5), molecular formula C27H39D7O2 and molecular weight 409.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7β-Hydroxycholesterol-25,26,26,26,27,27,27-d7 (C27H39D7O2) 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.
CATO manufactures 7β-Hydroxycholesterol-25,26,26,26,27,27,27-d7 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.
