For occupational chemical analysis use NIOSH: Methyl Chloride, 1001.

The Methyl chloride, with the CAS registry number 74-87-3 and EINECS registry number 200-817-4, has the systematic of chloromethane. And the molecular formula of this chemical is CH₃Cl. It is the most abundant organohalogen-anthropogenic or natural–in the atmosphere. It is a kind of colourless gas with a minorly sweet odor, and belongs to the following product categories: Refrigerants; Organics; CCosmetics; CFCsAlphabetic; Allergens; Alpha Sort; C; CH; Volatiles/ Semivolatiles; Alkyl; Halogenated Hydrocarbons; Organic Building Blocks. In addition, it should be stored at 2-8°C.

The physical properties of Methyl chloride are as following: (1)ACD/LogP: 1.11; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.113; (4)ACD/LogD (pH 7.4): 1.113; (5)ACD/BCF (pH 5.5): 4.129; (6)ACD/BCF (pH 7.4): 4.129; (7)ACD/KOC (pH 5.5): 96.046; (8)ACD/KOC (pH 7.4): 96.046; (9)#H bond acceptors: 0; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 0; (12)Polar Surface Area: 0 Å²; (13)Index of Refraction: 1.331; (14)Molar Refractivity: 11.531 cm³; (15)Molar Volume: 56.427 cm³; (16)Polarizability: 4.571×10^-24cm³; (17)Surface Tension: 14.643 dyne/cm; (18)Density: 0.895 g/cm³; (19)Enthalpy of Vaporization: 21.902 kJ/mol; (20)Vapour Pressure: 4074.091 mmHg at 25°C.

Preparation of Methyl chloride: Large amounts of Methyl chloride are produced naturally in the oceans by the action of sunlight on biomass and chlorine in sea foam. However, all Methyl chloride that is used in industry is produced synthetically. It can be prepared by reacting methanol with hydrogen chloride:
CH₃OH + HCl → CH₃Cl + H₂O

Uses of Methyl chloride: It was widely used as refrigerant, but due to its toxicity and flammability, its use has been discontinued. It is used as a chemical intermediate in the production of silicone polymers. It is also used as a solvent in the manufacture of butyl rubber and in petroleum refining. What's more, it also used as a methylating and chlorinating agent in organic chemistry.

You should be cautious while dealing with this chemical. It is a kind of extremely flammable chemical, and has danger of serious damage to health by prolonged exposure through inhalation. What's more, it may cause carcinogenic effect. Therefore, you had better take the following instructions: Keep container in a well-ventilated place; Keep away from sources of ignition - No smoking; Take precautionary measures against static discharges.

You can still convert the following datas into molecular structure:
(1)SMILES: CCl
(2)InChI: InChI=1/CH3Cl/c1-2/h1H3
(3)InChIKey: NEHMKBQYUWJMIP-UHFFFAOYAW
