Chemical Properties

CLEAR COLOURLESS LIQUID

Uses

4-Chloro-1-butanol was employed as an internal standard in the analysis of genotoxic impurities in active pharmaceutical ingredients by GC-MS technique.

Uses

4-Chloro-1-butanol is employed as an internal standard in the analysis of genotoxic impurities in active pharmaceutical ingredients by GC-MS technique.

Uses

Tetramethylene chlorohydrin is used inorganic synthesis.

Definition

ChEBI: A primary alcohol that is butan-1-ol substituted by a chloro group at position 4.

General Description

4-Chloro-1-butanol, an alkylating agent, is one of the genotoxic impurity in active pharmaceutical ingredients. Reaction of 4-chloro-1-butanol and Reichardt′s dye has been monitored spectrophotometrically for the determination of genotoxic impurities in pharmaceuticals.

Health Hazard

The toxicity of this compound is low. How ever, the acute toxic symptoms are those ofethylene and propylene chlorohydrins. Oralintake of this compound caused muscle con traction, gastrointestinal pain, ulceration, andliver injury in test animals.
LD50 value, oral (mice): 990 mg/kg
Tetramethylene chlorohydrin caused tumorsin lungs in test animals. Its carcinogenicity,however, is not yet fully established.

Fire Hazard

Flammable; flash point 36°C (97°F); vapor density 3.7 (air = 1); the vapor forms an explosive mixture with air, range is not reported. Fire-extinguishing agent: “alcohol” foam; a water spray may be used to cool fire-exposed containers and to flush any spill. It decomposes to HCl and tetrahydrofuran on heating.

Waste Disposal

Tetramethylene chlorohydrin is burned ina chemical incinerator equipped with anafterburner and scrubber.
