Subnitrate de bismuth CAS 1304-85-4 : formule, identification et approvisionnement<\/h1>\n

Bismuth subnitrate is the Longchang product record for CAS 1304-85-4.<\/strong> PubChem CID 73415757 identifies the CAS record with molecular formula Bi5<\/sub>H9<\/sub>N4<\/sub>O22<\/sub> and molecular weight 1461.99 g\/mol. A buyer should still match the name, CAS number, composition convention and approved specification before accepting a commercial material.<\/p>\n

Is bismuth subnitrate the same as bismuth oxynitrate?<\/h2>\n

\u201cBismuth oxynitrate\u201d and \u201cbismuthyl nitrate\u201d may appear as names associated with bismuth subnitrate records. A shared or related name does not make the name alone sufficient for procurement. Registry databases contain multiple bismuth subnitrate-related records and formula representations, so the inquiry should identify CAS 1304-85-4 and state the required composition or analytical convention.<\/p>\n

The term \u201cbismuthyl\u201d by itself is especially broad. Include the complete product name, CAS number and required specification, then reconcile any alternate name before sampling, labeling or ordering.<\/p>\n

For other bismuth identities, see the bismuth citrate identity guide<\/a> et bismuth subsalicylate specification guide<\/a>. Keep each material\u2019s CAS number and assay basis separate when comparing documents.<\/p>\n

How to read the Longchang source-record specification<\/h2>\n

The published product record lists an assay reported as Bi2<\/sub>O3<\/sub> of at least 79%, together with checks for carbonate, chloride, sulfate, ammonium salts, arsenic, copper, lead, silver, alkalis and alkaline earths. These are historical source-record fields; they are not a blanket release promise and do not establish which analytical method applies to a new inquiry.<\/p>\n

For qualification, request the specification and current-lot COA for the exact material being quoted. Compare units, assay basis, limits and test methods. If the buyer specification uses a different formula, hydration state or reporting basis, identify the difference before supplier approval.<\/p>\n

What \u201cuses\u201d information belongs in a sourcing decision?<\/h2>\n

A raw-material supplier page cannot determine whether a material is suitable, approved or correctly used in a finished formulation or destination market. The intended application should instead be translated into measurable grade, impurity, documentation, packaging and regulatory requirements. Suitability remains subject to the buyer\u2019s technical, quality and regulatory review.<\/p>\n

This page does not provide medical treatment, dosage, administration, side-effect or patient-safety advice. Website content is not a substitute for an authorized finished-product label, a current SDS or qualified professional review.<\/p>\n

Safety, storage and documentation<\/h2>\n

Use the current supplier SDS and a site-specific risk assessment to select engineering controls, personal protective equipment, storage, transport and disposal procedures. The Longchang source record describes sealed storage away from light and heat; confirm the current storage statement, packaging and shelf-life or retest information for the quoted material.<\/p>\n
