Ammonium Formate CAS 540-69-2: Formula, Molecular Weight and Sourcing

Ammonium formate is the ammonium salt of formic acid. Its CAS number is 540-69-2, its molecular formula is CH₅NO₂, and its molecular weight is 63.056 g/mol. Buyers should confirm the required grade, assay method, impurity limits, packaging and current document availability before ordering.

Ammonium formate identity

Identity values above are referenced to the PubChem compound record for ammonium formate (CID 2723923).

What is the molecular weight of ammonium formate?

The molecular weight of ammonium formate is 63.056 g/mol. Some technical documents round this to 63.06 g/mol. For calculations, use one convention consistently and follow the precision required by your analytical or manufacturing procedure.

What is the formula of ammonium formate?

The molecular formula is CH₅NO₂. It is also commonly represented as NH₄HCOO to show the ammonium and formate ions. The formula should not be confused with the specification of a commercial lot; assay, water and impurity limits require a current COA.

Properties buyers should confirm

Published reference values can vary by source, test method, concentration and temperature. Before selecting material, ask the supplier to confirm:

• assay and the analytical method used;
• water or loss-on-drying limit;
• appearance and solution clarity requirements;
• pH test concentration and method, when relevant;
• impurity and metal limits required by the application;
• storage conditions, packaging and retest or expiry information;
• availability of a current COA, SDS or technical data sheet.

Common technical uses

Ammonium formate may be evaluated as a laboratory reagent, a buffer component, a reagent in chemical synthesis or an intermediate in industrial processes. Suitability depends on the grade, impurity profile and process requirements. This page does not represent regulatory approval for pharmaceutical, food, feed or other regulated use.

Safety and handling

Use the current supplier SDS and a site-specific risk assessment before handling ammonium formate. Appropriate engineering controls, personal protective equipment, storage conditions and disposal procedures depend on the form, quantity and process. Do not rely on a general product guide as a substitute for the SDS.

Request current product information

Review the Longchang Ammonium Formate CAS 540-69-2 product record, then send the required grade, specification, quantity and destination to info@longchangchemical.com. Current specifications, documents, packaging and lead time are confirmed against the requested lot and destination.

Frequently asked questions

Is ammonium formate acidic or basic?

The measured pH of an ammonium formate solution depends on concentration, purity, temperature and method. Specify the test concentration and acceptable range instead of relying on a single generic pH value.

Is ammonium formate soluble in water?

Ammonium formate is described as water-soluble, but a quantitative solubility requirement should state the solvent, temperature and test method. Ask for supporting data when solubility is critical to the application.

Which documents should a buyer request?

Typical requests include a current-lot COA and SDS. A technical data sheet, analytical method or additional regulatory documentation should be requested only when required; availability must be confirmed for the specific product and market.
