TCI D4163 Desogestrel is a synthetic steroid compound belonging to the progestin class, supplied as a pharmaceutical research reagent intended strictly for experimental purposes and not for use as a drug in humans or animals. In the laboratory, this compound serves as a reference material and test substance in studies that investigate steroid hormones, ranging from work on progesterone receptor mechanisms through to the development of analytical methods. Its availability as a research-grade reagent allows experimental results to be verified and compared between laboratories with an adequate level of confidence.

The property that makes it a frequent choice is its rigid, well-defined steroid framework, carrying a characteristic substitution pattern that distinguishes it from other generations of progestins. As a steroid compound it is lipophilic and generally poorly soluble in water, yet soluble in polar organic solvents such as ethanol, methanol, or dimethyl sulfoxide, so it is easily prepared as a stock solution for both cell-based assays and instrumental analysis. The clarity of its chemical identity makes this compound dependable for use as a standard for identification and quantification in analytical work.

In Indonesian laboratories, this reagent is typically used in academic and institutional research settings where steroid hormone activity is the subject of study, and in analytical laboratories that require a well-characterised reference substance for method work. It supports receptor mechanism investigations, comparative studies across progestin structures, and the establishment of identification and quantification procedures — all within an experimental-use-only framework, never for administration to humans or animals.

  • Progesterone receptor mechanism studies — the well-defined steroid framework and clear chemical identity allow receptor binding and response behaviour to be examined against a dependable, reproducible test substance.
  • Analytical method development — the compound's unambiguous chemical identity makes it suitable as a reference substance when establishing and validating identification procedures for steroid hormones in the laboratory.
  • Quantitative analysis and calibration work — as a research-grade reagent with a defined identity, it serves reliably as a standard for quantification during instrumental analytical work.
  • Cell-based assay preparation — its solubility in polar organic solvents such as ethanol, methanol, or dimethyl sulfoxide allows straightforward preparation of stock solutions for experimental cell assays.
  • Comparative progestin structure research — the characteristic substitution pattern distinguishing it from other progestin generations makes it useful for structure-oriented comparative studies of steroid hormone compounds.
