1,2,3,4-Butanetetracarboxylic Acid (BTCA) sourcing overview
This 1,2,3,4-Butanetetracarboxylic Acid (BTCA) page organizes the identity and procurement fields needed for a clear B2B enquiry. CAS 1703-58-8 is the catalog reference, while grade, assay basis, physical format, impurity limits and supporting evidence must be confirmed for the specific offer.
Procurement context: An acid-form listing should state whether the free acid, a salt, a solution or another derivative is required, together with assay method and concentration or solvent basis where applicable.

Identity details to preserve
- Exact catalog name: Use “1,2,3,4-Butanetetracarboxylic Acid (BTCA)” as the initial requested name and resolve any supplier synonym to the same documented identity.
- CAS screening reference: The catalog associates 1703-58-8 with this listing. Verify the number on the offered specification, SDS and COA before approval.
- Written alias or qualifier: Keep the parenthetical text “BTCA” in the enquiry until current supplier documentation confirms its exact role.
- Written form or source terms: The name explicitly includes Acid. Preserve these terms and ask the supplier to define their analytical or compositional basis.
How to specify 1,2,3,4-Butanetetracarboxylic Acid (BTCA)
Use numerical acceptance limits and named test methods wherever they matter. The following fields help turn a name-only enquiry into a comparable specification brief.
- Exact acid form: Confirm free acid versus salt, ester, solution or hydrate and state stereochemistry where relevant.
- Assay and acidity: Define assay or concentration, acid value or titration basis, pH conditions and test method as applicable.
- Impurity profile: Set related substances, water, residual solvents, colour and other critical impurity limits.
- Physical criteria: State solid or solution form, particle size, concentration, solvent system, density or solubility requirements.
- Commercial scope: Provide grade, quantity, packaging compatibility, storage, destination and document requirements.
Documents and sample review
For a proposed 1,2,3,4-Butanetetracarboxylic Acid (BTCA) option, request the current product specification and a representative or recent certificate of analysis. Ask which supporting files are applicable and available, such as an SDS, TDS, origin statement, allergen or GMO statement, residual-solvent data, contaminant testing and destination-market compliance documents.
Evaluate documentation and a representative sample against the buyer’s own analytical, formulation, processing, stability, safety and regulatory criteria before bulk approval. Document and sample availability is confirmed for each enquiry.
Comparing 1,2,3,4-Butanetetracarboxylic Acid (BTCA) quotations
Why distinguish the free acid from salts or solutions?
The free acid, a salt and a formulated solution can differ in formula basis, concentration and handling. State the exact form, assay basis and solvent or hydration state so quotations are comparable.
Is CAS 1703-58-8 enough to approve the material?
No. A CAS number helps screen identity, but it does not define commercial grade, concentration, physical form, impurity limits, test methods, packaging or regulatory support. Compare those fields on the offered specification and COA.
