Phenolphthalein Supplier in Malaysia
- Also known as
- Phenolphthalein Indicator
- PP
Phenolphthalein supplier for laboratory, water-testing, construction, pharmaceutical, food QC and oil laboratory buyers in Malaysia. Also called phenolphthalein indicator and abbreviated PP in many titration procedures, this acid-base indicator is ordered as powder or as a prepared alcoholic solution.
Commercial forms include white to pale yellow crystalline powder and ready-to-use indicator solution, commonly at about 0.5% or 1% in ethanol or isopropanol. Technical and analytical reagent grades differ in assay and melting-range controls, so state the grade and any method specification with the enquiry.
Laboratories use phenolphthalein for acid-base titration endpoints, water and wastewater alkalinity checks, concrete carbonation-depth testing, and routine QC in pharmaceutical, food and petrochemical settings. It is not the same product as methyl orange, bromothymol blue or universal indicator.
Send the required form, grade, solution concentration if liquid, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.

Phenolphthalein grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Phenolphthalein powder | white to pale yellow crystalline powder or crystals | — | Laboratory and plant make-up of indicator solutions where the buyer prepares the alcoholic reagent on site for acid-base titration and QC. | Confirm the required pack format with the quotation. |
| Phenolphthalein indicator solution | clear alcoholic solution, commonly 0.5% or 1% in ethanol or isopropanol | — | Ready-to-use acid-base indicator for titration endpoints, water testing and routine QC where a prepared liquid is preferred over dissolving powder. | Confirm the required pack format with the quotation. |
| Analytical reagent phenolphthalein | high-purity powder or prepared indicator solution as specified | — | Analytical and QC work that specifies tighter assay, melting range or impurity controls than a general technical grade. | Confirm the required pack format with the quotation. |

Phenolphthalein applications
Safety and handling
Keep powder sealed in a cool, dry place away from moisture and strong oxidisers. Store indicator solutions in tightly closed containers, protect from evaporation and light as required by the grade, and follow the safety information supplied with the quotation. Supply is subject to applicable requirements.
Common questions about phenolphthalein
Do you supply phenolphthalein powder and indicator solution?
Both the solid powder or crystals and the pre-made alcoholic indicator solution are commercial market forms of phenolphthalein. State powder or solution, and for liquids the target concentration and solvent, so the quotation can match the requirement. Availability is confirmed with the quotation.
What concentration is common for phenolphthalein indicator solution?
Laboratory indicator solutions are commonly prepared at about 0.5% or 1% in ethanol or isopropanol. Confirm the exact strength and solvent against your method or specification rather than assuming a default value.
Is phenolphthalein the same as other pH indicators?
No. Phenolphthalein is a specific acid-base indicator identity and should not be substituted for methyl orange, bromothymol blue, universal indicator or other dyes without checking the method. Order the named indicator your procedure requires.
Which industries use phenolphthalein in Malaysia?
Analytical and QC laboratories use it for acid-base titration across manufacturing, water and wastewater testing, pharmaceutical and food QC, oil and gas laboratories, and concrete carbonation-depth checks on construction sites.
What details are needed for a phenolphthalein price enquiry?
Provide the form or grade, solution concentration and solvent if liquid, application, quantity and delivery location. Mention any preferred pack format, documentation needs and timing so the quotation can cover the full requirement.
Can documentation and packing be requested with the quotation?
Yes. List the product documents and preferred pack format in the enquiry. Available documentation, packing and commercial details are confirmed for the quoted powder or indicator solution grade.
