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.

General description
Application
- A study on titanium dioxide nanoparticles synthesized from titanium isopropoxide under SILAR-induced gel method: Transition from anatase to rutile structure: This research explores the synthesis and phase transition of titanium dioxide nanoparticles from anatase to rutile structure using the SILAR-induced gel method (AC Nkele et al., 2020).
- Synthesis of rutile TiO2 nanostructures by single step hydrothermal route and its characterization: This article describes the synthesis of rutile TiO2 nanostructures using a single-step hydrothermal method and their characterization (SB Wategaonkar et al., 2020).
- Monolayer Intermixed Oxide Surfaces: Fe, Ni, Cr, and V Oxides on Rutile TiO2(011): The study investigates the formation of mixed oxide layers on rutile TiO2(011) and their structural properties (S Halpegamage et al., 2016).
- Mechanism, thermodynamics and kinetics of rutile leaching process by sulfuric acid reactions: This research examines the dissolution of rutile in sulfuric acid, focusing on the thermodynamics and kinetics of the process (AV Dubenko et al., 2020).
- Kinetics of anatase transition to rutile TiO2 from titanium dioxide precursor powders synthesized by a sol-gel process: This paper studies the phase transition kinetics of anatase to rutile TiO2 from sol-gel synthesized precursor powders (CL Wang et al., 2016).

How can I determine the shelf life / expiration / retest date of this product?

What is the Particle size distributions or atleast Mean particle size of these rutile nano particles. Whether this is hydrophobic or hydrophilic in nature?
1 answer-
The mean particle size of this product is less than or equal to 100 nm, as listed in the properties section of the product page. However, no testing has been done to determine a distribution. Rutile Titanium(IV) oxide is generally considered hydrophilic due to its surface characteristics, which can interact favorably with water molecules.

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
