Chemical Structure

all-trans-Retinoic Acid-d5 (major) CAS 78996-15-3 chemical structure

Description

The occurrence of all-trans-Retinoic Acid-d5 (major) is closely related to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies all-trans-Retinoic Acid-d5 (major) (CAS 78996-15-3), a certified reference material (molecular formula C20H23D5O2, MW 305.47 g/mol) for analytical method development and quality control.

all-trans-Retinoic Acid-d5 (major) (C20H23D5O2) 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 all-trans-Retinoic Acid-d5 (major) 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.
