Description
4-MERCAPTO-1-BUTANOL, also known as 4-mercaptobutanol, is an organic compound with the chemical formula CH3CH2CH(OH)CH2SH. It is a colorless to slightly yellowish liquid with a strong, unpleasant odor. 4-MERCAPTO-1-BUTANOL is characterized by the presence of a thiol (-SH) group, which provides it with unique chemical properties and reactivity.
Uses
Used in Electronics Industry:
4-MERCAPTO-1-BUTANOL is used as a capping agent for the synthesis of metal nanoparticles, such as Highly Concentrated Nano-Au and Nano-Ag "Inks". The hydrophilic sparse ionic monolayer formed by 4-MERCAPTO-1-BUTANOL protects the metal nanoparticles, allowing them to be sintered at relatively low temperatures (150 °C) to achieve near-bulk conductivity. This application is particularly useful in the development of conductive inks for printed electronics and other related applications.
Used in Chemical Synthesis:
4-MERCAPTO-1-BUTANOL can be used as a reagent in various chemical synthesis processes due to its reactive thiol group. It can be employed in the production of various organic compounds, including pharmaceuticals, agrochemicals, and specialty chemicals, where its unique properties can be exploited to facilitate specific reactions or improve product yields.
Used in Analytical Chemistry:
The thiol group in 4-MERCAPTO-1-BUTANOL makes it a useful compound for the detection and quantification of heavy metals, such as mercury, lead, and cadmium, through techniques like atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP-MS). The strong affinity of the thiol group for heavy metals allows for selective complexation and subsequent detection or separation of these toxic elements from various samples.
Used in Cosmetics and Personal Care Industry:
4-MERCAPTO-1-BUTANOL can be used as a preservative in the cosmetics and personal care industry. Its antimicrobial properties help to prevent the growth of bacteria, fungi, and other microorganisms in products like lotions, creams, and shampoos, thereby extending their shelf life and ensuring product safety.
Check Digit Verification of cas no
The CAS Registry Mumber 14970-83-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,9,7 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 14970-83:
(7*1)+(6*4)+(5*9)+(4*7)+(3*0)+(2*8)+(1*3)=123
123 % 10 = 3
So 14970-83-3 is a valid CAS Registry Number.

Paragraph 0035; 0036, (2017/05/02)
The present invention discloses a 4-mercapto-1-butanol synthesis process, which comprises: 1) dissolving 1,4-butanediol and an acid-binding agent in an organic solvent I, adding a sulfonylation agent in a dropwise manner to carry out a sulfonylation reaction, carrying out extraction separation with dichloromethane, and carrying out washing, drying and concentration to obtain a colorless oil-like substance; and 2) dissolving the colorless oil-like substance obtained in the step 1) in an organic solvent II, adding a nucleophile to carry out a nucleophilic substitution reaction, and finally carrying out pressure reducing distillation to obtain the 4-mercapto-1-butanol. According to the present invention, the completely-new 4-mercapto-1-butanol synthesis route is provided, the used raw materials are easy to obtain, the operation is simple, the reaction conditions are not harsh, and good industrial values are provided.
Sulfoboration of Cyclic Ethers - A Preparative Route to Mercaptoalkanols and Bis(hydroxyalkyl) Sulfides

, p. 835 - 842 (2007/10/02)
Bis(1,5-cyclooctanediylboryl) sulfide (1) reacts slowly with the cyclic ethers A-D to give O,S-bis(9-BBN)mercaptoalkanols 2a-d in excellent yields.From oxetane (E) and 1, however, 2e is obtained rapidly, which further reacts with E to yield the bis(9-BBN-oxypropyl) sulfide 3ee. 2a and c react with E to form the mixed thioethers 3ae and 3ce, respectively.The methanolysis of 2a-e leads to the O-(9-BBN)mercaptoalkanols 4a-e.The compounds 2 and 3 react with acetylacetone or with 2-aminoethanol to yield the mercaptoalkanols 7a-c, e and the bis(hydroxyalkyl) sulfides 8ae, 8ce and 8ee, resp., in high yields beside the 9-BBN-chelates 5 or 6.Key Words: Ethers, cyclic, cleavage of / Sulfoborations / Mercaptoethanols, 9-BBN derivatives of / Sulfides, bis(hydroxyalkyl), 9-BBN derivatives of
