2-Phenylethanethiol / 2-Phenylethyl Mercaptan CAS 4410-99-5 For Enhancing Flavor in Meat and Savory Flavors (beef, chicken, pork) Roasted and Grilled Flavor Profiles Soups, Bouillons, and Seasoning

2-Phenylethanethiol is widely used in the food industry as a savory flavor ingredient. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) evaluated it in 1999 and concluded there is "no safety concern at current levels of intake when used as a flavouring agent" .

Key applications include:

• Meat and savory flavors (beef, chicken, pork)

• Roasted and grilled flavor profiles

• Soups, bouillons, and seasonings

• Where a cooked meat character is desired

Typical usage concentration: Extremely low levels (parts per billion to low parts per million) due to its high odor potency.

2-Phenylethanethiol serves as a valuable building block in organic synthesis to incorporate a thiol functional group into molecules . Specific research applications include:

• Synthesis of gold nanoclusters: Used in the preparation of biicosahedral Au₂₅ clusters protected with various types of thiol ligands 

• Mass spectrometry: Employed as a derivatization reagent for phosphorylated peptide sequences to enhance ionization efficiency in matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) 

• Spectroscopic studies: Structures of 2-phenylethanethiol and its water clusters have been studied using resonant two-photon ionization spectroscopy 

Due to its distinctive sulfurous, rubbery character, the compound is occasionally utilized in:

• Savory fragrance compositions

• Novelty scents

• Industrial fragrance formulations where specific olfactory notes are required
