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 Etaqualone-d3 Hydrochloride (Major).
Etaqualone-d3 Hydrochloride (Major) (CAS 1794789-34-6) is a high-purity analytical reference standard with the molecular formula C17H13D3N2OHCl and a molecular weight of 303.80 g/mol.
Structurally, Etaqualone-d3 Hydrochloride (Major) (C17H13D3N2OHCl) contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 303.80 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Etaqualone-d3 Hydrochloride (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.
