541-91-3 Usage

Chemical Properties

Different sources of media describe the Chemical Properties of 541-91-3 differently. You can refer to the following data:
1. Muscone is an odoriferous constituent of natural musk. It is a colorless liquid with very soft, sweet, musky odor and a perfumery, animal tonality.Numerous syntheses have been developed for its preparation including enantioselective methods to obtain the naturally occurring (3R)-enantiomer (l-muscone,. Because of its excellent stability, it can be used in awide range of products to give elegant,warm, animal notes. It is important for the reconstitution of naturalmusk.
2. Musk is secreted exclusively by the male animals of Moschus moschiferus, a wild deer living in themountains of Nepal,Tibet, and Mongolia.Thelight yellow secretion with a salve consistency accumulates in the abdominal pouch and probably serves to attract the females. When the pouch is dried, the secretion solidifies to form a brittle, brown mass with a characteristic odor. Since several Moschus species occur, large variations exist in the quality and specifications of musk. Hunting of the animals has been prohibited; therefore, only small quantities ofmusk are occasionally offered at extremely high prices. In the United States and Europe, naturalmusk is no longer used as a fragrance ingredient.
3. 3-Methyl-1-cyclopentadecanone has a soft, sweet, tenacious, musky odor.

Flammability and Explosibility

Notclassified

Biological Activity

muscone is a potent anti-inflammatory agent, which has been implicated in reducing proinflammatory cytokines and end-plate degeneration [1]. muscone is a territorial releaser pheromone in moschus moschiferus. muscone is not produced by humans. muscone is animal pheromone with no effects on humans comparable to those of androstadienone [2]. (±)-muscone is an odoriferous constituent of musk, a glandular secretion originally collected from the male musk deer [3].

Safety Profile

Low oral and skin contact toxicity. A skin irritant. A flammable liquid. When heated to decomposition it emits acrid smoke and irritating fumes.

in vitro

muscone reversed il-1β-induced upregulation of il-1β, tumor necrosis factor α, cyclooxygenase 2, inducible nitric oxide synthase, matrix metalloproteinase 13, aggrecanase 2, and nitric oxide and downregulation of col2α1 and aggrecan. in end-plate cartilage cultures, pretreatment with muscone (6.25, 12.5, 25 μmol/l) inhibited the il-1β-induced phosphorylation of extracellular signal-regulated kinases 1/2 and c-jun n-terminal kinase in a dose-dependent manner [1].

in vivo

in a rat model with induced intervertebral disc degeneration, muscone inhibited the expression of prostaglandin e2, 6-keto-prostaglandin f1α, il-1β, and tumor necrosis factor α and recovered the structural distortion of the degenerative disc [1].

Check Digit Verification of cas no

The CAS Registry Mumber 541-91-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 541-91:
(5*5)+(4*4)+(3*1)+(2*9)+(1*1)=63
63 % 10 = 3
So 541-91-3 is a valid CAS Registry Number.
