The theoretical percentage of titanium present in a 100% pure compound is calculated using the ratio of titanium molecular weight to titanium(IV) ethoxide molecular weight, resulting in 21.0%. This specification is set accordingly. A titanium amount of 35% would indicate a significant presence of titanium impurity. The test method details are not disclosed, as the product is of M-Clarity quality level MQ100.

Aplicación
Titanium(IV) ethoxide can be used:
- As an activator and dehydrating agent for by condensation of (S)-(+)-p-toluenesulfinamide with aldehydes and ketones to form sulfinimines.[1]
- As a Ti4+ ion source to form complexes of titanium (IV) acrylate with methacrylic acid.[2]
- As a catalyst to synthesize esters of sterically hindered alcohols via transesterification reactions.[3]
Precaución
During storage a gelatinous residue may form, which dissolves after heating up to 40 °C

Your Gravimetric Assay is listed as 20.5–21.5%, but I’ve seen 35% typically indicate 100% purity. How is this measured? Does it refer to TiO₂ after heating, or is another method used?

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

안녕하세요. 해당 제품의 specification sheet에는 gelation이 일어나며 40도 이상으로 가열하면 사라진다고 명시되어 있습니다. 제품의 인화점이 42도라고 적혀있습니다. 혹시 안전하게 가열할 수 있나요? 해당 제품은 수분에 민감하게 반응하는 것으로 알고 있는데 가열을 위해 약품통에서 꺼내는 순간 변질이 일어날 것 같습니다. 해당 제품의 gelation문제를 안전하고 변질없이 해결할 방법이 있나요?
1 answer-
Yes, it can be heated above 40 °C safely. This product is packaged in an argon gas environment. It is recommended to re-dissolve the gelation under inert gas (e.g., argon) protection with gentle heating.
