Pyridine serves as a solvent in the dyestuff and pharmaceutical sectors and functions as a laboratory reagent. Additionally, it plays a role in producing drug intermediates.

Grade 1: Suitable for analytical chemistry reagents and specific pharmaceutical preparations.

Grade 2: Intended for the manufacturing of drug intermediates.

Grade 3: Mainly utilized as a solvent in the dyestuff industry.

The substance should be a transparent liquid, devoid of any foreign particles, and possess the distinctive odor characteristic of pyridine. It must exhibit miscibility with water, alcohol, chloroform, and ether.

Upon testing as per the prescribed method, the material must conform to the requirements outlined in this standard.

TESTS

The subsequent test must be conducted for Pyridine.

• Solubility

• Identity and purity

• Relative Density

• Pyridine content

• Boiling Range

• Residue on evaporation

• Ammonium compounds

• Chlorides

• Copper

• Oxidizable substances

• Moisture content

PACKING AND MARKING

Packing and marking procedures must align with IS 8058:2018 standards. The material should be enclosed in mild steel drums, and the Standard Mark (ISI Mark) will be imprinted on the container only if the material meets all specification requirements.

Every container must display labels containing the required information as specified in the standard. Manufacturers are required to obtain a BIS license from the Bureau of Indian Standards to utilize a standard mark (ISI Mark). This license is granted following a comprehensive evaluation of manufacturing infrastructure, quality control measures, testing capabilities, and production processes.
