Bismuth Citrate CAS 813-93-4: Identity and Sourcing<\/h1>\n

Bismuth citrate is identified by CAS 813-93-4.<\/strong> PubChem CID 13135 reports molecular formula C6<\/sub>H5<\/sub>BiO7<\/sub> and molecular weight 398.08 g\/mol. The CAS number helps identify the substance, but it does not define a commercial grade, analytical method, regulatory status or document package.<\/p>\n

When comparing similarly named bismuth materials, consult the separate guides for bismuth subcitrate potassium<\/a> et bismuth subnitrate<\/a>. Match each inquiry to its own CAS number and specification; these links do not imply interchangeability.<\/p>\n

What does the Longchang source record contain?<\/h2>\n

The existing product record lists infrared identification, two additional identification checks, nitrate, arsenic, loss on drying, copper, lead, silver and bismuth assay on a dried basis. Its bismuth range is 49%\u201354%. These fields are historical website records, not a current-lot COA or an implied compendial claim.<\/p>\n

Several legacy acceptance descriptions say only that a test \u201cshould meet request.\u201d That wording does not define a method, unit or limit. Buyers should obtain the current specification and resolve every ambiguous entry before using it in a supplier-approval protocol.<\/p>\n

How should properties and intended applications be evaluated?<\/h2>\n

Translate the intended application into measurable identity, composition, impurity, physical-property, documentation, packaging and regulatory requirements. Do not infer suitability, approval, food status, pharmaceutical grade or finished-product performance from the chemical name or from a general applications article.<\/p>\n

This page does not provide treatment, dosage, administration, interaction, contraindication or patient-safety advice. It is a raw-material sourcing guide and is not a substitute for an authorized finished-product label, a current SDS or qualified regulatory review.<\/p>\n
