o-Toluenesulfonyl Chloride (2-Toluenesulfonyl Chloride ) CAS 133-59-5 Full Export Specification

1. Basic Chemical Identification

IUPAC Name: 2-methylbenzenesulfonyl chloride
Aliases: o-Toluenesulfonyl chloride, 2-Methylbenzenesulfonyl chloride, o-Tosyl chloride,
CAS No.: 133-59-5
EINECS: 204-028-8
MDL No.: MFCD00024874
Molecular Formula: $\boldsymbol{C_7H_7ClO_2S}$
Molecular Weight: 190.64
SMILES: CC1=CC=CC=C1S(=O)(=O)Cl
HS Code: 29049085
UN Number: UN 3265
IMDG Hazard Class: Class 8 Corrosive Liquid + Subsidiary 6.1 Toxic, Packing Group II
Signal Word: Danger

2. Physical & Chemical Properties

Appearance: Colorless to pale yellow transparent oily liquid, strong irritating acidic sulfonyl chloride odor; absorbs moisture in air to hydrolyze and release corrosive HCl gas, darkens gradually
Melting Point: 10–12 ℃
Boiling Point: 126–128 ℃ / 1.33 kPa; decomposes at high ambient pressure to release HCl
Density (20 ℃): 1.268–1.272 g/mL
Refractive Index n₂₀ᴰ: 1.5540–1.5570
Closed-cup Flash Point: >110 ℃
Vapor Pressure: Low volatility at room temperature; mist severely irritates respiratory tract and mucous membranes
Solubility: Insoluble in water, rapid hydrolysis to o-toluenesulfonic acid + hydrogen chloride; fully miscible with ethanol, acetone, toluene, dichloromethane, ethyl acetate, DMF
Stability:
- Highly sensitive to moisture; must be sealed under nitrogen protection to prevent hydrolysis
- Light-sensitive, avoid long-term sunlight exposure
- Incompatible with strong alkalis, amines, alcohols, oxidants, iron, copper, zinc alloys
Core Hazards
- Strong corrosive sulfonyl chloride; liquid and hydrolysis mist cause irreversible severe burns to skin, eyes and respiratory tract
- Toxic via skin absorption, inhalation and ingestion; long-term exposure damages liver and respiratory system
- Hydrolysis generates corrosive acid mist; high aquatic toxicity with bioaccumulation risk
