Deuterated 2-Chloroethanol-1,1,2,2-d4 | CAS 117067-62-6

Deuterated 2-Chloroethanol-1,1,2,2-d4 | CAS 117067-62-6 is a stable isotope-labelled analogue of 2-chloroethanol in which four hydrogen atoms are replaced with deuterium (^2H or D). This isotopically enriched compound retains nearly identical chemical behavior to its non-labelled counterpart while exhibiting a predictable mass shift of +4 Da (M+4), making it an excellent internal standard and reference material for advanced analytical applications. The compound has a molecular formula of C₂HClD₄O and a molecular weight of 84.54 g/mol. It is commonly supplied with approximately 98 atom % deuterium enrichment and high chemical purity for research applications.

Because the labelled analogue co-elutes with the target analyte while providing a distinct isotopic signal, it improves precision, reproducibility, and confidence in quantitative results.

Importance as an Internal Standard

Internal standards are essential in modern analytical chemistry because they compensate for variations introduced during sample preparation, extraction, injection, ionization, and instrument performance. Deuterated compounds provide superior correction compared to structurally unrelated compounds since they closely mimic the analyte throughout the analytical process.

Using Deuterated 2-Chloroethanol-1,1,2,2-d4 can help laboratories:

• Improve quantitative accuracy
• Correct matrix suppression or enhancement
• Minimize instrument-to-instrument variability
• Enhance method robustness
• Meet regulatory validation requirements
• Increase reproducibility across analytical batches

These characteristics make isotope-labelled standards indispensable in regulated pharmaceutical and bioanalytical laboratories.

Pharmaceutical Research Applications

Deuterated 2-Chloroethanol-1,1,2,2-d4 is valuable throughout pharmaceutical research and development. Scientists use isotope-labelled compounds during:

• Drug development programs
• Pharmaceutical impurity investigations
• Stability-indicating analytical methods
• Forced degradation studies
• Manufacturing process development
• GMP analytical testing
• Pharmacokinetic research
• Bioanalytical assay development
• Clinical sample analysis
• Reference standard qualification

Because isotope-labelled compounds closely resemble the native molecule, they provide exceptional analytical performance during method validation and routine quality control.

Role in Environmental and Toxicological Analysis

2-Chloroethanol and related chlorinated alcohols may require monitoring in environmental, industrial, and occupational settings. Deuterated standards improve trace-level quantification in complex matrices including water, soil, biological fluids, and industrial samples.

Applications include:

• Environmental residue monitoring
