114139 <common-name>Lead phosphite</common-name> <description>Lead phosphite is an inorganic compound with the formula H3O3P.xPb and an average molecular weight of 289.00 g/mol. Lead phosphite belongs to the post-transition metal phosphites, a subclass of post-transition metal oxoanionic compounds within the inorganic compounds. The substance is utilized across a wide range of plastics, including polypropylene, polystyrene, expanded polystyrene, polycarbonate, polyamide, polyurethane, acrylonitrile butadiene styrene, and polyvinyl chloride. It is also used in polyethylene terephthalate, high-density polyethylene, and low-density polyethylene, and is present in high impact polystyrene. Lead phosphite is found in or released from four recorded sources. These include fencing within the building and construction sector, as well as electrical and electronic equipment such as antennas, communication cables or conductors, and power cables.</description> <cas>16038-76-9</cas> <pubchem-id>6336625</pubchem-id> <chemical-formula>H3O3P.xPb</chemical-formula> <weight>289.0</weight> <appearance nil="true"/> <melting-point nil="true"/> <boiling-point nil="true"/> <density nil="true"/> <solubility nil="true"/> <specific-gravity nil="true"/> <flash-point nil="true"/> <vapour-pressure nil="true"/> <route-of-exposure nil="true"/> <target nil="true"/> <mechanism-of-toxicity nil="true"/> <metabolism nil="true"/> <toxicity nil="true"/> <lethaldose nil="true"/> <carcinogenicity nil="true"/> <use-source nil="true"/> <min-risk-level nil="true"/> <health-effects nil="true"/> <symptoms nil="true"/> <treatment nil="true"/> <created-at type="dateTime">2026-04-05T21:45:33Z</created-at> <updated-at type="dateTime">2026-04-17T15:34:22Z</updated-at> <interacting-proteins nil="true"/> <wikipedia nil="true"/> <uniprot-id nil="true"/> <kegg-compound-id nil="true"/> <omim-id nil="true"/> <chebi-id nil="true"/> <biocyc-id nil="true"/> <ctd-id nil="true"/> <stitch-id nil="true"/> <drugbank-id nil="true"/> <pdb-id nil="true"/> <actor-id nil="true"/> <organism nil="true"/> <export type="boolean">true</export> <metabolizing-proteins nil="true"/> <transporting-proteins nil="true"/> <moldb-smiles>OP(O)O.[Pb]</moldb-smiles> <moldb-formula>H3O3P.xPb</moldb-formula> <moldb-inchi>InChI=1/H3O3P.Pb.2H/c1-4(2)3;;;/h1-3H;;;/q;+4;;/rH3O3P.H2Pb/c1-4(2)3;/h1-3H;1H2/q;+4</moldb-inchi> <moldb-inchikey>UMKARVFXJJITLN-UHFFFAOYSA-N</moldb-inchikey> <moldb-average-mass type="decimal" nil="true"/> <moldb-mono-mass type="decimal">289.95863</moldb-mono-mass> <origin nil="true"/> <state nil="true"/> <logp nil="true"/> <hmdb-id nil="true"/> <chembl-id nil="true"/> <chemspider-id nil="true"/> <structure-image-file-name nil="true"/> <structure-image-content-type nil="true"/> <structure-image-file-size type="integer" nil="true"/> <structure-image-updated-at type="dateTime" nil="true"/> <biodb-id nil="true"/> <synthesis-reference nil="true"/> <structure-image-caption nil="true"/> <chemdb-id>CHEM110032</chemdb-id> <dsstox-id nil="true"/> <toxcast-id nil="true"/> <stoff-ident-origin nil="true"/> <stoff-ident-id nil="true"/> <susdat-id>NS00087208</susdat-id> <iupac>lead phosphite</iupac> <moldb-polar-surface-area nil="true"/> <moldb-refractivity nil="true"/> <moldb-polarizability nil="true"/> <moldb-rotatable-bond-count nil="true"/> <moldb-acceptor-count nil="true"/> <moldb-donor-count nil="true"/> <moldb-pka-strongest-acidic nil="true"/> <moldb-pka-strongest-basic nil="true"/> <moldb-physiological-charge nil="true"/> <moldb-number-of-rings nil="true"/> <moldb-alogps-logp nil="true"/> <moldb-alogps-logs nil="true"/> <moldb-alogps-solubility nil="true"/> <kingdom>Inorganic compounds</kingdom> <superklass>Mixed metal/non-metal compounds</superklass> <klass>Post-transition metal oxoanionic compounds</klass> <subklass>Post-transition metal phosphites</subklass> <paper-count type="integer">3429</paper-count> <sync-id>CED0005192</sync-id> <structure-inchikey>UMKARVFXJJITLN-UHFFFAOYSA-N</structure-inchikey> <structure-fingerprint>400000000000000000000000000000000000100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000010000000000000000000000000000000000000000000000000000000000000000000000000000000000014000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000</structure-fingerprint> <structure-pattern-fingerprint>40000000000400000000000000000000000000000000000000000000000000004000000004000000000000000000000000100000000000042000000000000000000020000000000000000000000000000000000000000400000000000000000000000010000000010000200400000040000000000000000000000100000024000000000000a0000000000024000000000000010000800000000000040000000000000000000000000000008000000040000000000000000000000000000000000400000002000000000000000000000000000000000000000000000000000004000000000000010000000</structure-pattern-fingerprint> <structure-pickle type="binary" encoding="base64">776t3gAAAAAQAAAAAwAAAAAAAAAFAAAAAwAAAIABCABgAAAAAQEPACAAAAAD CABgAAAAAQEIAGAAAAABAVIggAAAAAQLAAEAAQIAAQMAQgAAAAAXBAAAAAAA AAAW </structure-pickle> <structure-indexed-at type="dateTime">2026-09-19T04:43:46Z</structure-indexed-at> </compound>
