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 trans-7,8-Dihydroxy-7,8-dihydrobenzo[a]pyrene-d.
CATO supplies trans-7,8-Dihydroxy-7,8-dihydrobenzo[a]pyrene-d (CAS 861441-06-7), a certified reference material (molecular formula C20H6D8O2, MW 294.37 g/mol) for analytical method development and quality control.
trans-7,8-Dihydroxy-7,8-dihydrobenzo[a]pyrene-d (C20H6D8O2) contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 trans-7,8-Dihydroxy-7,8-dihydrobenzo[a]pyrene-d 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.
