Chemical Structure
Description
7-Acetamido-d3 Clonazepam (1.0mg/ml in Acetonitrile) (CAS 1330166-04-5), molecular formula C17H11D3ClN3O2 and molecular weight 330.78 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 7-Acetamido-d3 Clonazepam (1.0mg/ml in Acetonitrile) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 7-Acetamido-d3 Clonazepam (1.0mg/ml in Acetonitrile) 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.
