This white powder is widely used as a corrosion resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment (see also red lead). It has largely displaced toxic materials based on lead or chromium, and by 2006 it had become the most commonly used corrosion inhibitor. Zinc phosphate coats better on a crystalline structure than bare metal, so a seeding agent is often used as a pre-treatment.

Vanadium(III) sulfate is the inorganic compound with the formula V2(SO4)3. It is a pale yellow solid that is stable to air, in contrast to most vanadium(III) compounds. It slowly dissolves in water to give the green aquo complex [V(H2O)6]3+. The compound is prepared by treating V2O5 in sulfuric acid with elemental sulfur:Robert T. Claunch, Mark M. Jones "Vanadium(III) Sulfate" Inorganic Syntheses, 1963, Volume 7, pages 92–94. :V2O5 \+ S + 3 H2SO4 → V2(SO4)3 \+ SO2 \+ 3 H2O This transformation is a rare example of a reduction by elemental sulfur.

Chromium(III) boride, also known as chromium monoboride (CrB), is an inorganic compound with the chemical formula CrB. It is one of the six stable binary borides of chromium, which also include Cr2B,Cr5B3, Cr3B4, CrB2, and CrB4. Like many other transition metal borides, it is extremely hard (21-23 GPa), has high strength (690 MPa bending strength), conducts heat and electricity as well as many metallic alloys, and has a high melting point (~2100 °C). Unlike pure chromium, CrB is known to be a paramagnetic, with a magnetic susceptibility that is only weakly dependent on temperature.

Wolffram’s Red Salt is an inorganic compound with the double salt formula [Pt(C2H5NH2)4Cl2][Pt(C2H5NH2)4]Cl4·4H2O. This compound is an early example of a one-dimensional coordination polymer, serving as a representative structure for studies in solid-state physics. This species has been of interest due to the unusual mixed valence system of Pt(II) and Pt(IV) bridged by a chlorine atom. The deep red color of the double salt, where the components were colorless, piqued the interest of early inorganic chemists and ultimately inspired studies into the physical properties of the compound in search of potential applications.

In chemical nomenclature, the IUPAC nomenclature of inorganic chemistry is a systematic method of naming inorganic chemical compounds, as recommended by the International Union of Pure and Applied Chemistry (IUPAC). It is published in Nomenclature of Inorganic Chemistry (which is informally called the Red Book).Nomenclature of Inorganic Chemistry IUPAC Recommendations 2005 - Full text (PDF) 2004 version with separate chapters as pdf: IUPAC Provisional Recommendations for the Nomenclature of Inorganic Chemistry (2004) Ideally, every inorganic compound should have a name from which an unambiguous formula can be determined. There is also an IUPAC nomenclature of organic chemistry.

Phosphorus monoxide is an unstable radical inorganic compound with molecular formula PO. Phosphorus monoxide is notable as one of the few molecular compounds containing phosphorus that has been detected outside of Earth. Other phosphorus containing molecules found in space include PN, PC, PC2, HCP and PH3. It was detected in the circumstellar shell of VY Canis Majoris and in the star forming region catalogued as AFGL 5142. The compound has been found to have been initially produced in star-forming regions, and speculated to be carried by interstellar comets throughout outer space, including to the early Earth.

In biology, carbon source refers to the molecules used by an organism as the source of carbon for building its biomass. A carbon source can be an organic compound or an inorganic compound. Heterotrophs needs organic compounds as source of carbon and source of energy, while autotrophs can use inorganic compounds as carbon source and an abiotic sources of energy, as light (photoautotrophs) or inorganic chemical energy (chemolithotrophs). The biological use of carbon is part carbon cycle, where it starts from an inorganic source of carbon, such as carbon dioxide, that passes through the process of carbon fixation.

Hexachlorophosphazene is an inorganic compound with the formula (NPCl2)3. The molecule has a cyclic backbone which can be described as consisting of alternating single and double bonds between phosphorus and nitrogen atoms (hence classified as a phosphazene). It can be viewed as a trimer of the hypothetical compound N≡PCl2 (phosphonitrilic chloride; hence the alternative, more archaic name phosphonitrilic chloride trimer for compound). Hexachlorotriphosphazene together with the related octachlorotetraphosphazene (NPCl2)4 are precursors to inorganic polymers called polyphosphazenes, and is also the most common starting material for the study of substituted cyclophosphazene compounds.Mark, J. E.; Allcock, H. R.; West, R. “Inorganic Polymers” Prentice Hall, Englewood, NJ: 1992. .

Vanadium(III) iodide is the inorganic compound with the formula VI3. This paramagnetic solid is generated by the reaction of vanadium powder with iodine at around 500 °C. The black hygroscopic crystals dissolve in water to give green solutions, characteristic of V(III) ions.

Abū Mūsā Jābir ibn Hayyān (Arabic/Persian , often given the nisbas, al-Azdi, al-Kufi, al-Tusi or al-Sufi; fl. c. 721c. 815), is the supposed author of an enormous number and variety of works in Arabic often called the Jabirian corpus. The scope of the corpus is vast and diverse covering a wide range of topics, including alchemy, cosmology, numerology, astrology, medicine, magic, mysticism and philosophy. Popularly known as the father of chemistry, Jabir's works contain the oldest known systematic classification of chemical substances, and the oldest known instructions for deriving an inorganic compound (sal ammoniac or ammonium chloride) from organic substances (such as plants, blood, and hair) by chemical means.

It may also be characterized as intolerance causing hangover symptoms similar to the "disulfiram-like reaction" of aldehyde dehydrogenase deficiency or chronic fatigue syndrome. Severe pain after drinking alcohol may indicate a more serious condition. If people are intolerant, some nearly non-alcoholic beverages may be a problem, similar to alcohol-containing medications, vinegar, inhalation of alcohol or the vapour of alcohol-containing cleaning agents. Drinking alcohol first or afterwards together with Calcium cyanamide, an inorganic compound used as a fertilizer, can cause permanent or long lasting intolerance (nitrolime disease),Potential risks to human health and the environment from the use of calcium cyanamide as fertiliser, page 29, Scientific Committee on Health and Environmental Risks, Retrieved 14 November 2016 contributing together with other substances to the accumulation of harmful Acetaldehyde by inhibiting the enzyme acetaldehyde dehydrogenase.
