General description
Trichlorosilane is used as a reducing agent in certain chemical reactions or as a starting material for the synthesis of various organosilicon compounds. Trichlorosilane is generally used for the asymmetric hydrosilylation of olefins in the presence of palladium catalysts coordinated with chiral monodentate phosphorus ligands to generate chiral organosilanes.[1]
Application
Trichlorosilane has been used to synthesize 11-dicyclohexylphosphino-12-phenyl-9,10-dihydro-9,10-ethenoanthracene (H-KITPHOS) via reduction of 11-dicyclohexylphosphinoyl-12-phenyl-9,10-dihydro-9,10-ethenoanthracene.[2]
Other possible applications:
L-valine-derived catalyst to form secondary amines.[3]
derivatives is an effective reagent for the reduction of imines to form
enantiomerically enriched amines.[5][6]
Other possible applications:
- Asymmetric reduction of N-aryl ketimines in the presence of a novel
L-valine-derived catalyst to form secondary amines.[3]
- Hydrosilylation of imidazolinones to form chiral imidazolidinones in the presence of a 2,2′-bispyrrolidine based Lewis base organocatalyst.[4]
- Trichlorosilane activated with chiral N-formylproline
derivatives is an effective reagent for the reduction of imines to form
enantiomerically enriched amines.[5][6]
- Trichlorosilane reacts with dimethylformamide to form hypervalent hydridosilicates, which can reduce aldehydes to alcohols, imines to amines, and also for the reductive amination of aldehydes. [7]

Neurodegenerative diseases are characterized by oxidative stress, mitochondrial damage, and death of neuronal cells. To counteract such damage and to favor neurogenesis, neurotrophic factors could be used as therapeutic agents. Octadecaneuropeptide (ODN), produced by astrocytes, is a potent neuroprotective agent.

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

Do you have any pressure specifications for the SureSeal bottles in C20927043, particularly for product 175552-500G?
1 answer-
The inner packaging has undergone a hydrostatic pressure test. For the amber glass bottle PM1305 with SureSeal crown cap PM3314, a hydrostatic pressure test is conducted at 66 psi to ensure no leakage from the container.
