OVERVIEW

1,3,5-Trimethyl-1,3,5-triethyl-d6 cyclotrisiloxane | CAS 15901-49-2 is a high-purity, isotopically labeled cyclotrisiloxane designed specifically for analytical, research, and calibration applications. With six strategically incorporated deuterium atoms, this compound serves as an indispensable reference standard or internal standard in advanced mass spectrometry methodologies. The deuterium labeling enables excellent resolution from non-labeled analogs while preserving the chemical behavior and volatility required for reliable analytical performance.

This specialized organosilicon compound is commonly used in GC/MS calibration, method development, and quantitative analysis of siloxane contaminants or cyclic siloxane compounds in environmental and industrial samples. Its isotopic signature makes it uniquely valuable in laboratories where analytical precision, reproducibility, and trace-level detection are critical.

KEY APPLICATIONS  of  1,3,5-Trimethyl-1,3,5-triethyl-d6 cyclotrisiloxane | CAS 15901-49-2

Internal and Surrogate Standard in Mass Spectrometry

The deuterium incorporation shifts the mass spectrum in a predictable way, allowing this compound to act as an internal standard in GC/MS and LC/MS analyses without co-eluting with the unlabeled target analytes. This improves quantification accuracy, especially for trace-level detection.

Calibration & System Suitability Testing

Used for regular calibration of analytical instruments, particularly in environmental monitoring labs tracking siloxane pollutants or in semiconductor manufacturing analytics where cyclic siloxanes appear in process gases or waste streams.

Method Development & Validation

Ideal for developing robust analytical protocols for cyclic siloxanes, siloxane degradation products, or siloxane-related impurities. Its deuterated analog provides a reliable benchmark for assessing extraction efficiency, matrix effects, and instrument response reproducibility.

Research-Level Investigations

Used in polymer research and organosilicon chemistry studies to better understand reaction mechanisms, isotopic effects, and degradation pathways. Deuterium labeling assists in tracking molecular transformations via NMR and MS techniques.

ANALYTICAL BENEFITS OF DEUTERIUM LABELING

Enhanced Mass Spectrometry Performance

Deuterated standards simplify data interpretation by producing distinctive peaks separated by known mass differences from corresponding non-labeled compounds. This differentiation improves peak identification and quantitation precision.

Minimal Chemical Perturbation

Because deuterium is chemically similar to protium (¹H), labeled compounds retain virtually identical retention times to non-labeled analogs in GC and LC methods. This allows for accurate internal standards without drastically altering chromatographic behavior.

Reduced Matrix Interference

In complex sample matrices (e.g., wastewater, soil extracts, manufacturing effluents), using a labeled internal standard can compensate for signal suppression or enhancement, leading to more reliable quantitative results.
