Description

N-acetyl-DL-cysteine, also known as NAC, is a modified form of the amino acid cysteine. It is an antioxidant and a precursor to the antioxidant glutathione, which plays a crucial role in the body's detoxification processes. NAC has various applications in different industries due to its unique properties and potential health benefits.

Uses

Used in Pharmaceutical Industry:
N-acetyl-DL-cysteine is used as a reagent for the synthesis of phenylalkyl isoselenocyanates, which have demonstrated anticancer activity. This application highlights NAC's role in the development of potential cancer treatments and its contribution to the pharmaceutical industry.
Used in Antioxidant and Detoxification:
NAC is used as a supplement to support the body's natural antioxidant and detoxification processes. It helps maintain the balance of glutathione, which is essential for neutralizing harmful free radicals and toxins in the body.
Used in Respiratory Health:
N-acetyl-DL-cysteine is used to support respiratory health, particularly in conditions like chronic obstructive pulmonary disease (COPD) and cystic fibrosis. Its mucolytic properties help break down and clear mucus from the airways, improving lung function and overall respiratory health.
Used in Liver Health:
NAC is used to support liver health by aiding in the detoxification process and protecting liver cells from damage. It has been shown to be beneficial in the treatment of acetaminophen overdose and certain liver diseases.
Used in Skin Care:
In the cosmetic industry, N-acetyl-DL-cysteine is used as an ingredient in skincare products for its antioxidant and anti-aging properties. It helps protect the skin from environmental damage and supports the skin's natural repair processes.

Check Digit Verification of cas no

The CAS Registry Mumber 7218-04-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,1 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7218-04:
(6*7)+(5*2)+(4*1)+(3*8)+(2*0)+(1*4)=84
84 % 10 = 4
So 7218-04-4 is a valid CAS Registry Number.

Reaction of ascorbic acid with S-nitrosothiols: Clear evidence for two distinct reaction pathways

Holmes, Anthony J.,Williams, D. Lyn H.

, p. 1639 - 1644 (2007/10/03)

Ascorbate reacts with S-nitrosothiols generally, in the pH range 3-13 by way of two distinct pathways, (a) at low [ascorbate], typically below ~1 × 10-4 mol dm-3 which leads to the formation of NO and the disulfide, and (b) at higher [ascorbate] when the products are the thiol and NO. Reaction (a) is Cu2+-dependent, and is completely cut out in the presence of EDTA, whereas reaction (b) is totally independent of [Cu2+] and takes place readily whether EDTA is present or not. For S-nitrosoglutathione (GSNO) the two reactions can be made quite separate, although for some reactants the two reactions overlap. In reaction (a), ascorbate acts as a reducing agent, generating Cu+ from Cu2+, which in turn reacts with RSNO forming initially NO, Cu2+ and RS-. The latter can then play the role of reducing agent for Cu2+, leading to disulfide formation. Ascorbate will initiate reaction when the free thiolate has initially been reduced to a very low level by the synthesis of RSNO from a large excess of nitrous acid over the thiol. Reaction (b) is interpreted in terms of nucleophilic attack by ascorbate at the nitroso-nitrogen atom, leading to thiol and O-nitrosoascorbate which breaks up, by a free-radical pathway, to give dehydroascorbic acid and NO. A similar pathway is the accepted mechanism in the literature for the nitrosation of ascorbate by nitrous acid and alkyl nitrites. The rate constant for the Cu2+-independent pathway increases sharply with pH and analysis of the variation of the rate constant with pH identifies a reaction pathway via both the mono- and di-anion forms of ascorbate, with the latter being the more reactive. As expected the entropy of activation is large and negative. Some aspects of structure-reactivity trends are discussed.
