1639-09-4 Usage

Chemical Properties

Different sources of media describe the Chemical Properties of 1639-09-4 differently. You can refer to the following data:
1. clear liquid
2. 1-Heptanethiol is a flammable, colorless liquid with a strong odor.
3. Colorless liquid, onion aroma.

Aroma threshold values

High strength odor, sulfurous onion type; recommend smelling in a 0.10% solution or less.

General Description

Colorless liquid with a strong unpleasant odor. Mp: -41.3°C; bp: 177°C. Density: 0.84 g cm-3. Insoluble in water.

Reactivity Profile

1-Heptanethiol is combustible (flash point at or above 100°F and below140°F). Incompatible with oxidizing agents, strong acids and strong bases, alkali metals, and nitric acid. Can react with water, steam or acids to produce toxic and flammable vapors. Reacts violently with powerful oxidizing agents such as calcium hypochlorite(Ca(OCl)2) to generate SOx. Reacts with hydrides to form flammable H2 gas; reacts with halogenated hydrocarbons to yield HX. Reacts exothermically with aldehydes. Emits toxic compounds of sulfur when when heated to decomposition.

Potential Exposure

Used as a chemical intermediate for fuels, dyes, pharmaceuticals; and to make other chemicals.

Shipping

UN1228 Mercaptans, liquid, flammable, toxic, n.o.s. or Mercaptan mixtures, liquid, flammable, toxic, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, 6.1-Poisonous materials, Technical Name Required.

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explo sions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, alkali metals and reducing agents.

Check Digit Verification of cas no

The CAS Registry Mumber 1639-09-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,3 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1639-09:
(6*1)+(5*6)+(4*3)+(3*9)+(2*0)+(1*9)=84
84 % 10 = 4
So 1639-09-4 is a valid CAS Registry Number.

Two-step three-component process for one-pot synthesis of 8-alkylmercaptocaffeine derivatives

Rad, M. N. Soltani,Maghsoudi

, p. 70335 - 70342 (2016/08/06)

A highly efficient, odourless and two-step three-component process for one-pot synthesis of some 8-alkylmercaptocaffeine derivatives has been described. The catalyst-free three-component reaction of alkyl bromides, thiourea, and 8-bromocaffeine gave 8-alkylmercaptocaffeine products in excellent to quantitative yields. In addition, the impact of parameters on sample reaction is discussed.

Synthesis and antifungal activities of alkyl N-(1,2,3-thiadiazole-4-carbonyl) carbamates and S-alkyl N-(1,2,3-thiadiazole-4-carbonyl) carbamothioates

Li, Zaifeng,Wu, Zengru,Luo, Fuying

, p. 3872 - 3876 (2007/10/03)

A series of alkyl N-(1,2,3-thiadiazole-4-carbonyl) carbamates and S-alkyl N-(1,2,3-thiadiazole-4-carbonyl) carbamothioates with unsubstituted or monobrominated straight chain alkyl groups were synthesized and evaluated as fungistatic agents against Gibberella zeae and Altemaria kikuchiana. These compounds showed variable antifungal activities at concentrations of 5 and 50 μg/mL The results showed that antifungal activities depended on the length of the alkyl chain with the optimal chain length of 6-11 carbons. Carbamic acid, (1,2,3-thiadiazole-4-ylcarbonyl)-, hexyl ester (4) showed a strong fungistatic activity against A. kikuchiana at both concentrations, with 90.7 and 54% growth inhibition at 50 and 5 μg/mL, respectively. Carbamic acid, (1,2,3-thiadiazole-4-ylcarbonyl)-, heptyl ester (5); Carbamic acid, (1,2,3-thiadiazole-4-ylcarbonyl)-, octyl ester (6); and Carbamic acid, (1,2,3-thiadiazole-4-ylcarbonyl)-, undecyl ester (9) showed strong fungistatic activity against G. zeae at both concentrations. Their growth inhibitions against G. zeae at the concentration of 5 μg/mL were 78, 63, and 59%, respectively.

Carbanions Derived from 2-Alkylthiobenzothiazoles. A Novel α-Lithiomethyl Mercaptan Synthon for Mercaptomethylation.

Katritzky, Alan R.,Aurrecoechea, Jose M.,Vazques de Miguel, Luis M.

, p. 769 - 774 (2007/10/02)

2-Methylthiobenzothiazole readily gives a methyl group lithio derivative which reacts cleanly with electrophiles.The products are conveniently converted into the corresponding thiols by BuLi at -78 deg C, and this sequence thus provides a convenient two-step mercaptomethylation procedure for alkyl halides, aldehydes, and ketones.
