40244-29-9 Usage

General Description

(E)-3-(2,6,6-Trimethyl-1-cyclohexen-1-yl)propenenitrile is a chemical compound with the molecular formula C12H17N. It is a colorless to pale yellow liquid with a pungent odor, and is primarily used as a flavoring and fragrance agent in the food and cosmetics industry. It is also known for its use as a volatile deodorant in the manufacture of air fresheners and deodorizers. Additionally, this compound has been found to have some insecticidal properties, making it useful in pest control applications. However, it is important to handle this chemical with care, as it can be irritating to the skin, eyes, and respiratory system, and has the potential to cause allergic reactions in some individuals.

Check Digit Verification of cas no

The CAS Registry Mumber 40244-29-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,4 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40244-29:
(7*4)+(6*0)+(5*2)+(4*4)+(3*4)+(2*2)+(1*9)=79
79 % 10 = 9
So 40244-29-9 is a valid CAS Registry Number.

Synthetic control of retinal photochemistry and photophysics in solution

Understanding how molecular structure and environment control energy flow in molecules is a requirement for the efficient design of tailor-made photochemistry. Here, we investigate the tunability of the photochemical and photophysical properties of the retinal-protonated Schiff base chromophore in solution. Replacing the n-butylamine Schiff base normally chosen to mimic the saturated linkage found in nature by aromatic amines results in the reproduction of the opsin shift and complete suppression of all isomerization channels. Modification of retinal by directed addition or removal of backbone substituents tunes the overall photoisomerization yield from 0 to 0.55 and the excited state lifetime from 0.4 to 7 ps and activates previously inaccessible reaction channels to form 7-cis and 13-cis products. We observed a clear correlation between the presence of polarizable backbone substituents and photochemical reactivity. Structural changes that increase reaction speed were found to decrease quantum yields, and vice versa, so that excited state lifetime and efficiency are inversely correlated in contrast to the trends observed when comparing retinal photochemistry in protein and solution environments. Our results suggest a simple model where backbone modifications and Schiff base substituents control barrier heights on the excited-state potential energy surface and therefore determine speed, product distribution, and overall yield of the photochemical process.
