Overview
Dienestrol Quality Control Sample is a certified reference material primarily used in analytical laboratories and pharmaceutical quality control processes. As a synthetic nonsteroidal estrogen, it serves as a critical benchmark for method validation and instrument calibration in hormone analysis. Developed to meet stringent ISO 17034 and ISO Guide 35 requirements, these QC samples provide laboratories with reliable comparators for ensuring measurement accuracy and reproducibility. The material typically undergoes extensive characterization including mass spectrometry, NMR, and chromatographic purity testing before certification.
Physical and Chemical Properties
Dienestrol exhibits characteristic physical properties including a defined melting point range and specific UV absorption spectra that facilitate identification. The quality control samples are formulated to maintain stability with minimal degradation when stored properly. The compound's phenolic hydroxyl groups contribute to its moderate polarity and solubility profile. Quality control samples are typically provided with documented spectral data (IR, UV-Vis) and chromatographic retention parameters to support method development and system suitability testing in HPLC and LC-MS applications.
Main Applications
In pharmaceutical manufacturing, dienestrol QC samples are essential for batch release testing of estrogen-containing medications and for stability studies. Clinical laboratories use them to validate estrogen assay methods in endocrine testing and therapeutic drug monitoring. Research applications include use as internal standards in mass spectrometry and for developing new analytical methods in forensic toxicology. The samples also serve important roles in method transfer between laboratories and during regulatory inspections to demonstrate analytical competence.
Safety and Storage
As a potential endocrine disruptor, dienestrol requires careful handling with appropriate personal protective equipment. Work areas should have proper ventilation, and exposure monitoring may be necessary in regular use environments. For long-term stability, samples should be stored in amber glass vials with PTFE-lined caps at controlled refrigeration temperatures. Manufacturers typically provide stability data and recommended expiration dates, though many laboratories implement periodic requalification testing of their reference materials.
B2B Procurement Guide
When procuring dienestrol QC samples, buyers should prioritize suppliers with ISO 17025 accredited testing capabilities. Key documentation requirements include certificates of analysis with batch-specific data, measurement uncertainty statements, and traceability to national or international standards. For method-specific applications, consider requesting custom-prepared samples at particular concentration levels or in specific matrices. Bulk purchases may offer cost advantages, but verify storage capacity and stability considerations. Lead times for certified reference materials can be significant, so plan procurement accordingly.
