(+)-1,2-Propanediol

(4254-15-3)
Propylene glycol has become widely used as a solvent, extractant, and preservative in a variety of parenteral and nonparenteral pharmaceutical formulations. It is a better general solvent than glycerin and dissolves a wide variety of materials, such as corticosteroids, phenols, sulfa drugs, barbiturates, vitamins (A and D), most alkaloids, and many local anesthetics.
As an antiseptic it is similar to ethanol, and against molds it is similar to glycerin and only slightly less effective than

2-Methylpyridine

(109-06-8)
Solvent; intermediate in the dye and resins industries.2-Methylpyridine is used as a solvent, or as a chemical intermediate in the dye and resin industries (Windholz et al 1983) or for pharmaceuticals and rubber (Hawley 1981). It is used to make 2-vinylpyridine which is in turn made into a terpolymer with styrene and butadiene. The latexes of these terpolymers are extensively employed in adhesives for bonding textiles to elastomers (Reinhart and Britelli 1981). It is also a chemical intermediat

Bulk drug intermediates are the drugs used as raw materials for the production of bulk drugs, or they can refer to a material produced during synthesis of an API that must undergo further molecular change or processing before it becomes an API.

More Information

Intermediates are unavoidable products of chemical reactions and are widely used in pharmaceuticals, materials, chemicals, and other industries.

In the pharmaceutical industry, an active pharmaceutical ingredient (API) is a product of a synthesis process that has been completed and is used in the manufacture of bulk drugs and intermediates are some chemical raw materials or chemical products used in the synthesis process of APIs.

The application industries of pharmaceutical intermediates mainly include antibiotics, anticancer drugs, cardiovascular drugs, neurological drugs, hormone drugs, and immunosuppression.

Functions of intermediates

Intermediates serve a variety of responsibilities in the drug production process.

● They can serve as a link between the API and the finished medicine. The drug production process can be broken down into multiple steps using intermediates, each requiring a different chemical.

● They can modify reaction conditions and synthesis pathways, increasing drug synthesis efficiency and yields.

● They can be employed to modify the purification, crystallization, and solid characteristics of medicines.
