Brief introduction

Thiourea is an organic sulfur compound with the formula SC(NH 2) 2 and the structure H 2 N−C(=S)−NH 2.

Its structure is similar to urea (H 2 N−C(=O)−NH 2), but oxygen atoms are replaced by sulfur atoms (as the thioprefix implies).

The properties of urea and thiourea are very different. Thiourea is an organic synthesis reagent.

Thiourea is a broad class of compounds with the formula SC(NHR)(NH 2), SC(NHR) 2, etc

Physical and chemical properties of Thiourea

       Is thiourea corrosive

1.Corrosiveness analysis
Weak acidity/reducing property
Thiourea aqueous solution is weakly acidic (pH≈6~7), and has no obvious corrosiveness to common metals such as steel and aluminum, but long-term contact may have a slight effect on metals like copper.

Reaction with oxidants:
Mixing with strong oxidants (such as hydrogen peroxide, sodium hypochlorite) may produce irritating gases (such as sulfur dioxide), and compatibility should be avoided.

2. Major safety risks
Toxicity (requires key prevention) :

Oral ingestion, inhalation or long-term skin contact may pose a threat to health (animal experiments have shown a carcinogenic risk, and the International Agency for Research on Cancer (IARC) has classified it as a Group 3 substance, meaning it is not yet clearly carcinogenic to humans).

It may irritate the eyes, skin and respiratory tract, and cause allergic reactions.

Environmental risk:
Thiourea degradation may produce toxic sulfur-containing compounds, and the waste liquid needs to be professionally treated.

3. Safety usage suggestions
Protective measures:

Wear gloves, goggles and dust masks when operating to avoid direct contact.

Ensure good ventilation, especially when heating or preparing solutions.

Storage conditions:

Store in a sealed container in a cool and dry place, away from oxidants and food.

4. The difference from corrosive substances
Different from strong acids/strong bases:
The corrosiveness of thiourea is much lower than that of strong acids such as hydrochloric acid and sulfuric acid, but its toxicity risk is more prominent and it should be managed as a hazardous chemical.
