Is ATMP acid the same as ATMP sodium salts?

No. ATMP acid, CAS 6419-19-8, and its mono-, tetra- or pentasodium salts have different CAS numbers, pH, active basis and sodium content. State acid or salt form, liquid or solid form, active concentration and target formulation before comparing quotations.

Which specifications should be compared for industrial ATMP?

Confirm active acid by the stated method, total phosphonic or phosphorus basis where used, phosphorous acid, chloride, iron, color, density and pH test conditions. Standard and low-chloride grades are not equivalent for every water-treatment or process use.

What is ATMP typically used for?

ATMP is evaluated as a phosphonate scale-control or metal-ion-complexing agent in water-treatment and industrial formulation systems. Performance depends on water chemistry, dosage, temperature, pH and the chosen salt form, so it should not be assumed from chemical identity alone.

What are the typical physical forms and properties of ATMP?

ATMP acid is available as a colorless to light-yellow liquid or white crystalline powder, with formula C3H12NO9P3, molar mass about 299.05 g/mol and common liquid density around 1.30-1.35 g/cm3. It is highly soluble in water, while organic-solvent solubility is limited, so confirm the offered form and concentration.

How should ATMP be stored and handled?

Store in tightly closed, compatible containers in a cool, dry, ventilated area. Avoid freezing or excessive heat for liquid grades, protect solids from moisture and caking, use chemical-resistant equipment during transfer, and follow the current safety information for PPE and spill response.

Product Description

Molecular formula: C₃H₁₂NO₉P₃.

CAS Number: 6419-19-8.

EC Number: 229-146-5.

Molar mass: 299.05 g/mol.

Application context

ATMP may be evaluated for metal-ion complexation in a defined water-system formulation.

Scale-control performance depends on water chemistry, dosage, system conditions, and product specification; do not assume a fixed result.

Corrosion-related performance must be confirmed for the target system; do not infer it from the chemical identity alone.

Packaging and storage

Handling, storage, and process requirements must be reviewed against the applicable SDS and current product-specific specification.
