Introduction

Organic Synthesis

A versatile isothiocyanate (-NCS) donor for synthesizing thioureas, thiazolinones, and intermediates in agrochemical/pharmaceutical industries.

Agrochemicals

Key in producing insecticides, herbicides (e.g., benzothiazoles), and plant growth regulators.

Polymer Chemistry

Acts as a crosslinker or functional monomer in polyurethanes, epoxy resins, and high-temperature polymers.

Conditions

Store in a tightly sealed, light-protected container under inert gas (e.g., nitrogen) at ≤4°C with ≤20% humidity.

Container

Use glass or HDPE; avoid contact with metals or rubber.

Stability

Moisture-sensitive; monitor purity due to hydrolysis to thiocyanic acid and propylamine.

Molecular Formula

C₄H₇NS

Molecular Weight

101.17 g/mol

Solubility

Soluble in ethanol, ether, chloroform; insoluble in water.

Reactivity

Reacts with amines to form thioureas and with alcohols under acidic conditions to yield thiolcarbamates.
