Safety Data Sheet

Getting an SDS for 1-Bromopropane

A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of 1-Bromopropane issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.

04 · Precautionary statements

1-Bromopropane precautionary statements

CLP Annex VI assigns 17 precautionary statements to 1-Bromopropane. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.

05 · Names in the regulation

1-Bromopropane name in 23 EU languages

CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

07 · Health hazards

1-Bromopropane health hazards and exposure limits

1-Bromopropane hazard summary

1-Bromopropane is a colorless liquid. Commercial 1-bromopropane includes not only 1-bromopropane, but also additives that improve its performance in the desired application and stabilizers to inhibit decomposition. 1-Bromopropane was originally used in the production of pesticides, flavors and fragrances, pharmaceuticals, and other chemicals.

1-Bromopropane carcinogenicity classification

IARC classification Group 2B — Possibly carcinogenic to humans
IARC monographs Volume 115: (2018) Some Industrial Chemicals

Under the conditions of these 2-year inhalation studies, there was some evidence of carcinogenic activity of 1-bromopropane in male F344/N rats based on the occurrence of rare adenomas of the large intestine and increased incidences of epithelial neoplasms of the skin (keratoacanthoma, squamous cell carcinoma, and basal cell neoplasms). Increased incidences of malignant mesothelioma and pancreatic islet adenoma may also have been related to 1-bromopropane exposure. There was clear evidence of carcinogenic activity of 1-bromopropane in female F344/N rats based on increased incidences of adenoma of the large intestine. Increased incidences of neoplasms of the skin may also have been related to 1-bromopropane exposure. There was no evidence of carcinogenic activity of 1-bromopropane in male B6C3F1 mice exposed to concentrations of 62.5, 125, or 250 ppm 1-bromopropane. There was clear evidence of carcinogenic activityof 1-bromopropane in female B6C3F1 mice based on increased incidences of alveolar/bronchiolar neoplasms.

Source: US National Toxicology Program · TR-564: Toxicology and Carcinogenesis Studies of 1-Bromopropane (CASRN 106-94-5) in F344/N Rats and B6C3F1 (Inhalation Studies) (2011 )

1-Bromopropane is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

Source: Hazardous Substances Data Bank (HSDB)

Evaluation: There is inadequate evidence in humans for the carcinogenicity of 1-bromopropane. There is sufficient evidence in experimental animals for the carcinogenicity of 1-bromopropane. Overall evaluation: 1-Bromopropane is possibly carcinogenic to humans (Group 2B).

Source: Hazardous Substances Data Bank (HSDB)

An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.

1-Bromopropane incompatible materials

Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. /Halogenated aliphatic compounds/

Source: Hazardous Substances Data Bank (HSDB)

1-Bromopropane reactivity

Halogenated aliphatic compounds, such as 1-BROMOPROPANE, are moderately or very reactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. Emits toxic fumes of bromine when burned.
