General description
Sodium phosphate is a colorless to white crystalline powder or granules. It is prepared by neutralization of phosphoric acid under controlled conditions with sodium hydroxide or sodium carbonate .
We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Sodium phosphate supports cleaner technologies as a versatile buffering and stabilizing agent that helps control pH, mitigate corrosion and side reactions, and extend equipment/component lifetimes—reducing waste, chemical use, and energy demand across processes.

Application
Sodium phosphate is used as a:
Other general uses are as pH control agent, water hardness precipitation, laboratory reagent, phosphatizing reagent.
- component in the preparation of solid crystals of calcium hydroxyapatite substituted by strontium
- block buffer to study segmental and subcellular distribution of CFTR in the kidney
Other general uses are as pH control agent, water hardness precipitation, laboratory reagent, phosphatizing reagent.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
