Hochreines

hochreines is a German adjective derived from the words hoch (high) and rein (pure). It is used to describe substances, materials, or products that possess an exceptionally high degree of purity, often exceeding the standard purity criteria set by industry or regulatory bodies. The term is commonly applied in scientific, industrial, and commercial contexts where contaminant levels must be minimized.

In the semiconductor and electronics industry, hochreines materials such as silicon, germanium, and various metals are essential for reliable fabrication of microchips and other high‑performance components. These materials must have impurity concentrations in the parts‑per‑billion range to avoid electrical leakage or degradation of device performance. Optical fibre manufacturing also demands hochreines glass with trace‑metal removal to achieve low attenuation.

The pharmaceutical sector uses hochreines reagents and solvents to meet Good Manufacturing Practice (GMP) standards. Any residual impurities can affect drug safety, efficacy, and shelf life, so chemical manufacturers provide hochreines grades that satisfy strict limits defined by the European Medicines Agency (EMA) and the U.S. Food and Drug Administration (FDA). Analytical chemistry laboratories also rely on hochreines water, typically with resistivity of 18.2 megohms·cm at 25 °C, to ensure accurate results in titrations, spectroscopy, and chromatography.

In addition to technical usage, hochreines is occasionally found as a brand name in the cleaning and household products sector, emphasizing the absence of harsh chemicals or residues. While the term itself is purely descriptive, it conveys a high standard of quality that is recognized across various professional fields.
