Chemical Products 2-Thiopheneethanol Product Usage
2-Thiopheneethanol is a thiophene derivative used in the preparation of oligothiophene isothiocyanates as fluorescent markers for biopolymers. 2-Thiopheneethanol is also used in the preparation of other biologically active compounds such as the analgesic Sulfentanyl and the antithrombotic Clopidogrel Hydrogen Sulfate (C587250).

Chemical Products 2-Thiopheneethanol Production Methods
Biotransformation experimentsFungal strains were pre-grown in Petri dishes containing maltextract solid medium (MEA: 20 g L−1 glucose, 20 g L−1 malt extract,20 g L−1 agar, 2 g L−1 peptone) from which the inoculum for liquidcultures was set up. The fungus was inoculated as conidia suspen-sion (1 106 conidia/mL) in 50 mL asks containing 40 mL of maltextract liquid medium. Flasks were incubated at 25 C and weremaintained under agitation (110 rpm).After 2 days of pre-growth, a 500 mM solution of the substratein DMSO was added, to a starting substrate concentration (c0) of1–5 mM. For each substrate, three biological replicates were run.The experiment was run for 3 days after the addition of the sub-strates, during which time 1 mL samples were taken, at speciedintervals (usually 24, 48, and 72 h). Each sample was extractedwith EtOAc (500 L), the organic phase was dried over anhydrousNa2SO4 and analysed by means of GC/MS. In some cases (see Section2.4) the isolation of the reduced product has been carried out.For each set of biotransformations, one ask was used to mea-sure the initial biomass and pH before the addition of the substrate.These parameters were also evaluated at the end of the experimentfor all the asks.
