Crystal arthropathy is a class of joint disorder (called "arthropathy"), which acid is characterized by accumulation of tiny crystals in one or more joints. Polarizing microscopy and application of other crystallographic techniques have improved identification of different microcrystals including monosodium urate, what is the heterocyclic compound of carbon, nitrogen, oxygen, and hydrogen with the formula CHNO?

Organomercury Organomercury refers to the group of organometallic compounds that contain mercury. Typically the Hg–C bond is stable toward air and moisture but sensitive to light. Important organomercury compounds are the methylmercury(II) cation, CHHg; ethylmercury(II) cation, CHHg; dimethylmercury, (CH)Hg, diethylmercury, and merbromin ("Mercurochrome"). Thiomersal is used as a preservative for vaccines and intravenous drugs.
