Specification and supply checklist

Acid identity and active content
Confirm whether your requirement is PBTC acid, CAS 37971-36-1, or a specified salt. State the target active content and reporting basis so different specifications can be compared consistently.
Appearance, impurities and test conditions
Provide the appearance or color limits and any impurity limits your process requires. Include the test-solution concentration for pH and the measurement temperature for liquid density, with the relevant methods.
Formulation and evaluation conditions
Identify oxidizing biocides and other formulation ingredients, operating conditions and the results your team needs to demonstrate. Provide a summary of the evaluation plan before requesting a sample discussion.
Documents and commercial requirements
List the TDS, SDS and batch-COA requirements, estimated quantity, packaging preference, destination and timing. The quotation review should confirm the selected grade, package and delivery terms together.

Start with your application

Cooling-water formulations

When reviewing PBTC for calcium carbonate scale control, include hardness, alkalinity, pH and temperature. Identify any oxidizing biocide, its operating concentration and dosing pattern, together with the other treatment components.

Industrial cleaning ingredients

PBTC is used as a sequestering ingredient in cleaning formulations. Share the target formulation pH, other ingredients, intended substrate and stability tests so the technical discussion reflects the finished product you plan to make.

Request the documents for your grade

Use the TDS for product review, the SDS for handling and regulatory review, and a relevant COA for batch-level checks.

PBTC buying questions

Do PBTC and PBTCA refer to the same product identity?

Both abbreviations are used for 2-phosphonobutane-1,2,4-tricarboxylic acid. This page identifies the acid with CAS 37971-36-1. Check the full name, acid or salt form and active-content specification when comparing quotations; an abbreviation alone does not define a grade.

What information is needed if my system uses an oxidizing biocide?

Provide the biocide identity, concentration or residual range, dosing pattern, operating pH and temperature, and the other treatment ingredients. These conditions allow a focused compatibility review. The product name alone does not establish suitability for your complete treatment program.

Is PBTC a complete cooling-water treatment formulation?

This catalog entry describes a chemical ingredient. A finished treatment program depends on water chemistry, system materials and the functions required, including any additional scale, deposit or corrosion control. State whether you are purchasing an ingredient for formulation or reviewing a treatment application.

How can I request PBTC documents and a quotation?

Send your required specification, intended use, quantity, preferred package and destination. Request the TDS and SDS for the grade under review, and identify the tests needed on a batch COA. Include your target timing so documents, sample evaluation and commercial terms can be discussed in the appropriate order.
