The Thiazolidine, with the CAS registry number 504-78-9 and EINECS registry number 208-002-5, has the systematic name and IUPAC name of 1,3-thiazolidine. It is a kind of clear colorless liquid, and belongs to the following product categories: Heterocyclic Compounds; Building Blocks; Heterocyclic Building Blocks; Thiazolines/Thiazolidines. And the molecular formula of the chemical is C₃H₇NS.

The characteristics of Thiazolidine are as followings: (1)ACD/LogP: -0.12; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -3.03; (4)ACD/LogD (pH 7.4): -1.57; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 1; (8)ACD/KOC (pH 7.4): 1; (9)#H bond acceptors: 1; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 0; (12)Polar Surface Area: 28.54 Å²; (13)Index of Refraction: 1.513; (14)Molar Refractivity: 25.34 cm³; (15)Molar Volume: 84.2 cm³; (16)Polarizability: 10.04×10^-24cm³; (17)Surface Tension: 37.5 dyne/cm; (18)Density: 1.058 g/cm³; (19)Flash Point: 56.1 °C; (20)Enthalpy of Vaporization: 40.1 kJ/mol; (21)Boiling Point: 164.5 °C at 760 mmHg; (22)Vapour Pressure: 1.96 mmHg at 25°C. 

It may be synthesized by a condensation reaction between a thiol and an aldehyde or ketone. The reaction is reversible. Therefore,many thiazolidines are labile towards hydrolysis in aqueous solution. Hydrolysis of the thiazolidine generates the thiol and aldehyde or ketone from which it was synthesized.

Uses of Thiazolidine: It can react with 4-cyano-benzenediazonium; tetrafluoroborate to produce 3-(p-cyanophenylazo)-1,3-thiazolidine. This reaction will need the menstruum acetone and H₂O. The reaction time is 0.5 hours with temperature of 0°C, and the yield is about 37%.

You should be cautious while dealing with this chemical. It may cause burns. Therefore, you had better take the following instructions: Wear suitable protective clothing, gloves and eye/face protection, and if in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice; In case of accident or if you feel unwell, seek medical advice immediately (show label where possible).
