Olanzapine-d3 | CAS 132539-06-1

Olanzapine-d3 is a stable isotope-labelled analogue of olanzapine that plays an essential role in modern bioanalytical and pharmaceutical testing. Incorporating three deuterium atoms into the olanzapine molecule, Olanzapine-d3 is primarily used as an internal standard for LC-MS/MS and LC-HRMS analysis, enabling highly accurate and reproducible quantification of olanzapine in biological matrices and pharmaceutical formulations. Stable isotope-labelled reference standards such as Olanzapine-d3 are indispensable for method development, method validation, pharmacokinetic studies, bioequivalence testing, therapeutic drug monitoring, forensic toxicology, and clinical research.

At ResolveMass Laboratories Inc., we provide high-quality isotope-labelled reference standards that support pharmaceutical companies, CROs, academic researchers, and clinical laboratories in achieving reliable analytical performance while meeting stringent regulatory expectations.

What is Olanzapine-d3?

Olanzapine-d3 is the deuterated analogue of olanzapine, an atypical antipsychotic medication widely prescribed for the treatment of schizophrenia and bipolar disorder. In Olanzapine-d3, three hydrogen atoms are replaced with stable deuterium (^2H) atoms, resulting in a compound that behaves almost identically to the native analyte during chromatographic separation while remaining distinguishable by mass spectrometry. Stable isotope-labelled compounds are considered the gold standard as internal standards because they effectively compensate for sample preparation losses, matrix effects, and instrumental variability.

Unlike radioactive isotopes, deuterium-labelled compounds are non-radioactive and chemically stable, making them suitable for routine analytical laboratories and regulated pharmaceutical environments.

Chemical Properties

Importance in LC-MS/MS Bioanalysis

Quantitative LC-MS/MS assays require internal standards that closely mimic the analyte throughout extraction, chromatography, and ionization. Olanzapine-d3 fulfills this requirement exceptionally well by exhibiting nearly identical physicochemical properties to unlabeled olanzapine while providing a distinct mass shift detectable by tandem mass spectrometry.

Using Olanzapine-d3 as an internal standard helps improve analytical accuracy by correcting for:

• Variability during sample extraction
• Matrix-induced ion suppression or enhancement
• Instrument response fluctuations
• Injection volume differences
• Sample preparation inconsistencies

These advantages contribute to improved precision, reproducibility, and regulatory compliance for quantitative bioanalytical methods.

Applications :

Olanzapine-d3 is widely employed across pharmaceutical research, clinical laboratories, and analytical testing facilities. Common applications include:

• LC-MS/MS assay development
• Bioanalytical method validation
• Pharmacokinetic (PK) studies
• Bioequivalence (BE) studies
• Therapeutic drug monitoring
• Clinical pharmacology research
• Toxicokinetic investigations
• Forensic toxicology
• Pharmaceutical quality control
• Stability studies
• Drug metabolism research
• Analytical method transfer between laboratories

Because isotope-labelled internal standards closely track the analyte during every analytical step, they significantly reduce variability and enhance data quality.

Role in Regulated Bioanalytical Studies

Regulatory agencies including the FDA, EMA, and Health Canada expect validated bioanalytical methods capable of generating accurate and reproducible quantitative data. Stable isotope-labelled internal standards are widely recommended because they minimize analytical variability and improve assay robustness.

Olanzapine-d3 supports validated bioanalytical methods used for:

• Clinical trial sample analysis
• Generic drug development
• New drug applications (NDA)
• Abbreviated New Drug Applications (ANDA)
• Therapeutic equivalence studies
• Pharmacokinetic and toxicokinetic evaluations

Its use contributes to consistent assay performance across large analytical batches and multiple validation runs.

Advantages of Using Olanzapine-d3

Selecting an isotope-labelled internal standard offers several analytical advantages over structurally unrelated compounds:

• Excellent chromatographic co-elution with olanzapine
• Nearly identical extraction recovery
• Reduced matrix effects
• Improved quantitative accuracy
• Superior method precision
• Enhanced reproducibility
• Increased confidence in low-level quantification
• Better compliance with regulatory bioanalytical guidelines

These characteristics make Olanzapine-d3 the preferred internal standard for highly sensitive LC-MS/MS methods.

Pharmaceutical Research Applications

Olanzapine remains one of the most extensively studied atypical antipsychotic agents. Consequently, Olanzapine-d3 supports numerous research programs, including:

• Drug absorption studies
• Distribution and metabolism investigations
• Pharmacokinetic modeling
• Drug-drug interaction studies
• Population pharmacokinetic research
• Personalized medicine initiatives
• Clinical biomarker studies
• Pharmaceutical formulation development

Researchers depend on isotope-labelled standards to produce reliable quantitative data that withstand scientific and regulatory scrutiny.

Analytical Compatibility

Olanzapine-d3 is compatible with multiple analytical platforms commonly used in pharmaceutical laboratories, including:

• LC-MS/MS
• UHPLC-MS/MS
• LC-HRMS
• Triple quadrupole mass spectrometry
• High-resolution Orbitrap systems
• QTOF mass spectrometry

These platforms enable highly selective and sensitive quantification of olanzapine across plasma, serum, urine, and other biological matrices.
