Aminoguanidine hydrochloride identity at a glance

External identity reference: PubChem CID 2734687. Commercial decisions must use the current supplier documents for the quoted material.

Are aminoguanidine hydrochloride and aminoguanidinium chloride the same?

For CAS 1937-19-5, PubChem groups Aminoguanidine Hydrochloride and Aminoguanidinium Chloride under CID 2734687. The parent compound aminoguanidine and other salt forms have different records. An RFQ should therefore state the complete chemical name, CAS number and required salt form instead of relying on a shortened name alone.

What should a buyer specify?

The chemical name and CAS number are only the identity layer. A purchasing specification should also define the required assay, analytical method, impurity limits, water or loss-on-drying basis, physical description, packaging, storage, labeling and document package.

The existing Longchang product record lists white powder, assay 98% min, total impurity ≤1%, heavy metals ≤10 ppm and packaging as “BAG.” These are historical source-record fields. They do not identify the current analytical methods, reporting basis, bag material or pack size and must be confirmed in the current specification and lot documentation.

How should intended use be evaluated?

The Longchang catalog classifies this material as a pharmaceutical intermediate. That category describes a possible supply-chain role; it does not establish pharmaceutical grade, approval, suitability for a finished drug or performance in a medical application. Buyers should translate the intended technical use into measurable material and regulatory requirements.

This page does not provide treatment, dosage, administration, efficacy, interaction or patient-safety advice. Research references to aminoguanidine do not qualify a supplier lot or authorize a finished product.

Documents and qualification checks

• current specification with revision, test methods, units and reporting basis;
• representative or current-lot COA, as applicable;
• current SDS and any available TDS;
• origin, manufacturing-site, change-control or questionnaire information required by the buyer;
• pack size, bag material, labeling, storage and transport requirements;
• sample terms and the evaluation protocol, when a sample is required.

Safety and regulatory boundary

Use the current supplier SDS and a site-specific risk assessment to select engineering controls, personal protective equipment, storage, transport and disposal procedures. Do not infer handling requirements, market authorization or regulatory status from this identity guide.
