Useful:

• Chemical Classes: Metals -> Chromium Compounds, Inorganic
• Canonical SMILES: [O-][Cr](=O)(=O)[O-].[Na+].[Na+]
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed.
• Effects of Short Term Exposure: The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. The substance may cause effects on the kidneys and liver. This may result in tissue lesions.
• Effects of Long Term Exposure: Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. Repeated or prolonged inhalation may cause nasal ulceration. This may result in perforation of the nasal septum. The substance may have effects on the kidneys. This may result in kidney impairment. This substance is carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
• Uses: Sodium chromate anhydrous is used as a corrosion inhibitor in the petroleum industry, wood preservative and dyeing auxiliary in the textile industry. It is also used to prepare pigments for paints and inks. It also finds use in pharmaceuticals to determine red blood cell volume. In synthetic chemistry, it is utilized as an oxidant to convert primary alcohols and secondary alcohols to carboxylic acids and ketones respectively. Diagnostic aid (blood volume determination); radioactive agent.
