Bismuth Subsalicylate CAS 14882-18-9: Identity and Sourcing

Bismuth subsalicylate is identified by CAS 14882-18-9. PubChem CID 53629521 reports molecular formula C₇H₅BiO₄ and molecular weight 362.09 g/mol. Buyers should use the CAS number together with an approved specification because chemical identity alone does not define the commercial grade, test methods or document set.

Bismuth subsalicylate identity at a glance

External identity reference: PubChem CID 53629521. Commercial release decisions must use the current supplier documents for the material under review.

Why the assay and specification basis matter

The existing Longchang source record contains a headline “99% min” assay field and a detailed table with separate ranges for bismuth by ignition and total salicylate. Those entries use different descriptions and cannot be treated as interchangeable without the applicable definition and method.

The same record lists identification, pH, loss on drying, nitrate, arsenic, free salicylate and bismuth-solubility checks. These are historical source-record fields, not a current-lot COA or an implied compendial claim. Before qualification, request the current specification, reporting basis and test methods for the quoted grade.

How should buyers evaluate intended use?

Translate the intended application into measurable grade, composition, impurity, documentation, packaging and regulatory requirements. A raw-material supplier page cannot establish whether a material is suitable, approved or correctly used in a finished product or destination market.

This page does not provide medical treatment, dosage, administration, interaction, contraindication or patient-safety advice. It is not a substitute for an authorized finished-product label, a current SDS or qualified professional review.

Documents to request

• current specification with test methods and reporting basis;
• representative or current-lot COA, as applicable;
• current SDS and any available TDS;
• origin, packaging and labeling details required by the qualification process;
• sample terms and any supplier questionnaire required before evaluation.

Safety and storage boundary

Use the current supplier SDS and a site-specific risk assessment to select engineering controls, personal protective equipment, storage, transport and disposal procedures. The source record describes cool, dry storage away from direct sunlight; confirm the current storage statement, shelf-life or retest information and packaging before ordering.

Frequently asked questions

What is the formula of bismuth subsalicylate CAS 14882-18-9?

PubChem CID 53629521 and the Longchang source record use C₇H₅BiO₄, with molecular weight 362.09 g/mol.

Why are several assay-related values shown?

The source record includes a headline assay plus separate bismuth-by-ignition and total-salicylate ranges. Ask for the current specification and methods to determine the reporting basis and which field applies to supplier approval.
