Buffer systems: compare pH response alongside the other acid and salt components.
SODIUM PHOSPHATES
Sodium Dihydrogen Phosphate MSP
An acidic sodium orthophosphate for buffering and phosphate-system comparisons.
INGREDIENT OVERVIEW
MSP: product profile
Sodium dihydrogen phosphate is monosodium phosphate, an orthophosphate distinct from DSP and TSP. Anhydrous and hydrated materials require their own form identification.
Also known as: MSP · Monosodium phosphate · Sodium phosphate monobasic · Sodium dihydrogen orthophosphate
MSP contributes to phosphate buffer systems where the balance of acidic and more alkaline components matters. We invite inquiries that describe the finished food, target pH behavior and the other salts already in the recipe.

GRADE & PROCESS
The acidic member of the sodium orthophosphate family
Choosing the material
Anhydrous, monohydrate and dihydrate materials differ in water content and mass basis. Product names on the sample, specification and quotation should identify the same form; equal weights of different hydrates are not automatically equivalent.
Planning a useful comparison
Compare pH after mixing and after the actual heating or holding step. In mineral- or protein-containing foods, also observe sediment, separation and texture under the same conditions.
GRADE & SPECIFICATION
Key parameters to confirm.
State the hydration form on the request and specification. Water of crystallization changes the mass basis; a common abbreviation is insufficient for a like-for-like comparison.
These are procurement questions, not a supplied specification. Units below indicate reporting context, not acceptance limits. Compare the current grade, source, document revision and test method before agreeing values.
If columns extend beyond the frame, scroll the table horizontally.
| Parameter | What to request | Units or test context | Why it matters |
|---|---|---|---|
| Form and assay basis | Salt identity, hydration and assay method | Named hydrate; stated mass basis | Keep form-dependent values separate. |
| Solution pH | Sample concentration, water and temperature | pH with preparation conditions | Compare buffer ingredients using equivalent tests. |
| Purity and insolubles | Current impurity limits and methods | Source-defined units and method | Match the intended grade and quality review. |
PURCHASING QUESTIONS
MSP: what to ask next.
Is MSP interchangeable with DSP?
No. Their acid-base behavior and sodium contribution differ. Compare the complete buffer recipe and the required hydration form.
What should accompany my inquiry?
Include the exact material and form, food application, destination market and target specification. Request current records for the proposed grade and source, and identify any methods your quality team requires.
Packaging, handling & ordering
Specify the hydration form and whether the material is dissolved or dry blended. Pack format and storage instructions should relate to that form and its proposed source.
Share your quantity and required delivery timing. Minimum order, sample terms, packing and the stated shelf life belong to the specific quotation and source records.
Identity reference points
These sources support technical identity checks. They do not establish a supplied grade, source approval or permission in every food or market.
DOCUMENT REQUEST
Request documents for MSP.
Tell us the material form, intended use, destination market and document purpose. Request Form-specific specification, current TDS and representative COA. Records depend on the proposed grade and source; any certificate applies only within its stated entity, site and product scope.
