Bromopentane

1-Bromopentane_110-53-2_High Purity Bromopentane_Pharmaceutical Intermediate

Core Product Parameters:

1-Bromopentane, also known as n-pentyl bromide, CAS: 110-53-2, molecular formula C5H11Br, molecular weight 151.05. It is a colorless transparent liquid and an important medium-to-long chain brominated alkane. Due to its specific lipophilicity and moderate reactivity, it is widely used as an efficient pentylating agent, reliably introducing the n-pentyl group into organic molecules, making it a crucial building block for synthesizing various functional compounds.

Specifications and Quality Control:

We provide high-purity 1-bromopentane products, with a standard specification of ≥99.0% (GC). Through strict distillation processes and quality control during production, the product features low color (APHA), low moisture (determined by Karl Fischer method), low acid value, and low impurity content, ensuring excellent reaction efficiency and product purity for key reactions such as nucleophilic substitution. Its outstanding batch-to-batch consistency meets the needs from laboratory research to industrial production.

Main Application Areas:

1-Bromopentane is a versatile and important fine chemical intermediate. Its main applications include:

Pharmaceutical and Pesticide Intermediates: As a key building block, it is used to synthesize a range of drug molecules (such as sedative-hypnotics) and highly effective, low-toxicity pesticides, introducing the pentyl chain to modulate biological activity.

Fragrance and Dye Synthesis: Used in synthesizing fragrance compounds with fruity and wine-like aromas, as well as dye intermediates with specific structures.

Functional Materials and Surfactants: As a precursor, it is employed in preparing specialty surfactants, functional polymer materials, and as a solvent and reagent in organic synthesis.

Scientific Research and Experiments: Widely used in organic synthesis research at universities, research institutions, and corporate R&D centers.

Usage, Storage, and Safety Guidelines:

This product is recommended for use in well-ventilated environments. Reactions should be conducted under base catalysis or inert gas protection, avoiding contact with strong oxidizing agents. Store sealed, away from light, in a cool, dry place. Operators must wear chemical-resistant gloves, goggles, and other personal protective equipment to avoid direct contact with skin and eyes. For comprehensive safety information, first aid measures, and disposal guidelines, please carefully review and follow the latest version of the MSDS (Material Safety Data Sheet) provided with the product before use.

Packaging, Logistics, and Technical Services:

We offer flexible packaging solutions: industrial-scale supply in 250kg/drum packaging, while for R&D and trial production needs, we supply reagent-grade small packages such as 100ml and 500ml, with professional repackaging services available. Each batch comes with complete quality documentation, including COA (Certificate of Analysis), MSDS (Material Safety Data Sheet), and third-party test reports upon request. Our professional technical service team can provide support for product application and process optimization.
