Chloromethane was a widely used refrigerant, but its use has been discontinued. It was particularly dangerous among the common refrigerants of the 1930s due to its combination of toxicity, flammability and lack of odor as compared with other toxic refrigerants such as sulfur dioxide and ammonia .

In chemistry, volatility is a material quality which describes how readily a substance vaporizes. At a given temperature and pressure , a substance with high volatility is more likely to exist as a vapour , while a substance with low volatility is more likely to be a liquid or solid .
According to the Oxford English Dictionary, the suffix ‘omics’ refers to ‘the totality of some sort’. In biology, ‘omics’ techniques are used for the high-throughput analysis of DNA sequences and epigenetic modifications (genomics), mRNA and miRNA transcripts (transcriptomics), expressed proteins (proteomics), as well as synthesised metabolites (metabolomics) in a biological system ...
Volatility (chemistry), a measuring tendency of a substance or liquid to vaporize easily Volatile organic compounds, organic or carbon compounds that can evaporate at normal temperature and pressure Volatile anaesthetics, a class of anaesthetics which evaporate or vaporize easily
Chloroform, [10] or trichloromethane (often abbreviated as TCM), is an organochloride with the formula C H Cl 3 and a common solvent.It is a volatile, colorless, sweet-smelling, dense liquid produced on a large scale as a precursor to refrigerants and PTFE. [11]
