763-20-2 Usage
Description
2-methylheptane-2-thiol is a straw-colored liquid characterized by a strong, obnoxious odor. It is highly toxic, being lethal through inhalation of even small amounts of vapor and also through skin absorption. Additionally, it acts as a skin and eye irritant. When exposed to high temperatures, it decomposes to produce toxic sulfur oxides and flammable hydrogen sulfide. It is less dense than water and has a flash point of 115°F.
Uses
Used in Lubricant Additives:
2-methylheptane-2-thiol is used as an additive in the lubricant industry to enhance the performance and properties of lubricants. Its application reason is to improve the lubricating qualities and ensure the smooth operation of machinery and engines.
Used in Polymer Modification:
In the polymer industry, 2-methylheptane-2-thiol is utilized for modifying polymers. It serves as a modifier to enhance specific characteristics of polymers, such as their flexibility, durability, or resistance to certain conditions, thus expanding their range of applications and improving their overall performance.
Reactivity Profile
Organosulfides, such as 2-methylheptane-2-thiol, are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid.
Check Digit Verification of cas no
The CAS Registry Mumber 763-20-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 763-20:
(5*7)+(4*6)+(3*3)+(2*2)+(1*0)=72
72 % 10 = 2
So 763-20-2 is a valid CAS Registry Number.

Structure-odor correlations in homologous series of alkanethiols and attempts to predict odor thresholds by 3d-qsar studies
Polster, Johannes,Schieberle, Peter
, p. 1419 - 1432 (2015/03/05)
Homologous series of alkane-1-thiols, alkane-2-thiols, alkane-3-thiols, 2-methylalkane-1-thiols, 2-methylalkane-3-thiols, 2-methylalkane-2-thiols, and alkane-1,??-dithiols were synthesized to study the influence of structural changes on odor qualities and odor thresholds. In particular, the odor thresholds were strongly influenced by steric effects: In all homologous series a minimum was observed for thiols with five to seven carbon atoms, whereas increasing the chain length led to an exponential increase in the odor threshold. Tertiary alkanethiols revealed clearly lower odor thresholds than found for primary or secondary thiols, whereas neither a second mercapto group in the molecule nor an additional methyl substitution lowered the threshold. To investigate the impact of the SH group, odor thresholds and odor qualities of thiols were compared to those of the corresponding alcohols and (methylthio)alkanes. Replacement of the SH group by an OH group as well as S-methylation of the thiols significantly increased the odor thresholds. By using comparative molecular field analysis, a 3D quantitative structure-activity relationship model was created, which was able to simulate the odor thresholds of alkanethiols in good agreement with the experimental results. NMR and mass spectrometric data for 46 sulfur-containing compounds are additionally supplied.
